What it is: D2 is a carbon tool steel with a relatively high chromium content, prompting some to call it a "semi-stainless" steel. Unfortunately a high amount of it decreases strength. For example, D2 has enough chromium to be stainless (~12%) but its high carbon means that too much chromium carbide is formed to leave enough chromium for stainless levels of corrosion resistance. whats even more disturbing is that cvn and fracture toughness sometimes (often?) 14C28N Vs 440C Knife - edcTopic.com Also Mo additions improve corrosion resistance for a given amount of chromium. Properties: 14C28N: D2: Edge retention: 4/10: 7/10: Ease of sharpening: 6/10: 3/10: Corrosion resistance: 4/10: 4/10: Toughness: I wrote an article about knife steel ratings available online in 2018, where I concluded that none of them were very good. Looks like there is no reason to us it over 420HC. The Vargo Sobata 398 is unlike any other knife on this list. Thanks Larrin, Check out theGiantMouse Vox/Anso ACE Iona Liner Lock Knife at $99, for example. While some are into that type of thing, if youre familiar with a specific steel and want to compare it with another, you should definitely click on that button below. XHP is an exceptionally well-balanced steel with excellent all-around attributes. Vanax gives up some toughness and hardness vs MagnaCut for saltwater levels of corrosion resistance. You can see that 64 Rc AEB-L has both lower toughness and edge retention than 61 Rc MagnaCut, so I feel that in general you get a better sense of where the steels fit with a single point. Its very similar chemically to RWL 34 and ATS-34. Powder metallurgy is a technology designed to maintain a small carbide size. you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. The steel loses some of the chromium in solution for corrosion resistance to form these fine carbides for hardness. Steels with only vanadium carbides have the best balance of properties because the hardness of carbide matters for edge retention but doesnt for toughness. I have a couple questions, not directly related to this specific post, that I wanted to ask publically so that others could find your responses as well, so here seemed as good a place as any. Interesting. S45VN Knife Steel - BladeReviews.com Manage Settings Sorry, most of my previous comment was borderline word salad. Below shows a comparison of carbide structure between D2 and CPM-D2, and then toughness measurements between the conventional and PM versions of CruWear, D2, and 154CM. 440C steel Most of the discussion of how the ratings were generated, various caveats and details, etc. can you strike twice as fast with the knife? Anyway, buff up the O1v and it cuts leather easily. Quite an eyeopener! We did the research to help you find the best hunting knife for your needs and budget. In particular, I have found the ESEE/Rowen 1095 to be less likely to chip and better at holding an edge than the KA-BAR version even in knives with the same role, thickness, and blade length. Does that mean that companies like Tops, Kabar and ESEE would be better off using 420HC instead of 1095 on their fixed blades? 2. What about K390? The best knife for you should meet your needs and fit your budget. 14c28n | Civivi Sandvik 14c28n Steel Review - KnifeUp One of the more common stainless steels, and one readily available in lots of different places worldwide, AUS-8 is a decent all-around steel. D2 is not a bad steel, but it has been around a long time and is somewhat mundane by current standards. Tanto VG-10 steel also has the same level of toughness as 14C28N and the same level of corrosion resistance. imo o lot depends on how the blade is sharpened. Mostly it has been presented piecemeal with all of the studies that we have done on optimizing heat treatments of different steels like CPM-CruWear, AEB-L, 52100, etc. Now that we know what each factor represents, we can see how the steels rank against one another. And below shows a chart of carbide hardness, the equation we created to predict edge retention based on edge angle, hardness, and carbide volumes, and then the chart showing the good correlation: TCC (mm) = -157 + 15.8*Hardness (Rc) 17.8*EdgeAngle() + 11.2*CrC(%) + 14.6*CrVC(%) + 26.2*MC(%) + 9.5*M6C(%) + 20.9*MN(%) + 19.4*CrN(%). : knife a with a toughness of 5 and an angle of 20 degrees will perform as well in edge retention as knife b with a toughness of 3 and an angle of 15 degrees. It is among the steel knives with exceptional toughness while maintaining excellent corrosion resistance. The D2, on the other hand, has a thicker and more durable blade that is better suited for tough tasks like chopping wood or prying open cans. And given the recipe, it has a low number of carbides, the extra-hard microcrystals in steel that provide the hardness necessary for a stable and sharp edge. A quick check shows the compositions of these steels are nearly identical, so based on that Id expect them to perform similarly (differences in heat treat and blade geometry aside). So presumably, wear resistance would be in the 3.5-4 range and toughness in the 5.5-6 range. Thanks! 440B This is the basis on which I do the ratings rather than a linear scale. CTS-204P and CPM-20CV are nearly identical steels made by other manufacturers. Lately Ive been edcing one of those instead of a nice folder. CPM-3V is a powder metallurgy contender in this category. It confirms what I always suspected and what anyone could have figured out by reading the technical data. 14C28N is a stainless steel that was developed specifically for use in knives. The table shows combinations of knife steel properties for different classes of steel. That said, it's not as tough as many other steels and exponentially tougher to sharpen. It has high levels of chromium and carbon, making it extremely resistant to corrosion. Should have a first draft by the end of next week. Thank you for such a great article! Steel with high wear resistance is more costly to manufacture, as the knife company goes through more abrasives to grind the knives. CPM-S90V is my favorite in the high edge retention category because of its decent toughness. my understanding is that wood is not a particularly abrasive material and a plane is more of a push cut action than a slicing action so I would have though edge stability and sharpness is more important than edge retention meaning ABE-L should work pretty well. This is a powder steel produced by American steel company Carpenter. Lets talk about the clip-on pocket knife. This does not predict which knife will cut longer or be more resistant to chipping. The steel is similar to Sandviks 13C26. Im not hating on 80crv2 , Ive used it. This is about comparing steels to each other rather than a limitation of an individual steel. Many custom makers enjoy AEB-L, as its easy to machine but still has a high hardness, around 62 HRc. Some steels are more difficult to manufacture for the steel company or have more expensive alloying elements so the cost is increased. Im not sure they answer my question, though, and some of your points dont seem to jive with the info here on Larrins site. False treatment and geometry upheld by Made in USA is like buying 8Cr from China (except late A.G) My personal experience tops with Vanadis 4E, CPM-M4, RWL-34 and the likes. Why do knives make the best gifts? You will get an ultra-sharp edge with 14C28N knives. 14C28N vs D2 - knifebasics.com If you want for best steel 14c28n and others steel then you can ready 14c28n vs 420hc review. Vancron has a very fine microstructure so it would be tough to beat. We looked at common steels used by popular knife brands to help you select the right material for your blade. It has excellent edge retention, corrosion resistance, and ease of sharpening. If you want to learn more than keep reading past the ratings. Very acute edges are more brittle but remain sharp for longer and cut very well. 14c28n Steel Review - Knives & Gear The best scenario is when the steel, heat treatment, and geometry are selected for the knife and the use. I like it in the Seki City Spydercos, but I would like to know what ratings you would give it. 14C28N is thus ideal for use in corrosive environments and challenging applications. The most balanced is CPM-MagnaCut which is in an area all by itself on the chart. 2. Often used for combat knives. It would be really useful to have the raw data that backs the charts that you produce. D2 knives, on the other hand, are challenging to sharpen. Stainless steels are more resistant to corrosion but remember that stainless steels stain less, and most of them will still rust in the right conditions. 1. It improves wear resistance and hardenability. That mixture has one goal in mind: making a great steel for people worried about rust and corrosion. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. I believe they are made of simple carbon steel. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. You cannot leave your 14C28N knives in water overnight and expect them not to rust. There has been some internet controversy over the grinding and heat treat of this steel. On the other hand small but mighty, the pocket knife provides both in professional performance and in arresting good looks. I always thought VG10 to be way more chippy/less tough compared cpms45vn. I have the average composition of the steels rated above (plus some extras) so you can see what the different names refer to. AEB-L and 14C28N also have moderate edge retention though of course much lower than vanadium-alloyed powder metallurgy steels like S30V or M390. MagnaCut has the lowest chromium of any of the below steels but all of its chromium is in solution (no chromium carbide) and the fact that it has no chromium carbide also gives it the maximum level of corrosion resistance for a given amount of chromium. What carbon/tool steel would you choose for a survival knife if a PM steel was too expensive? I can also say from personal experience that marine grade plywood will chaw up your saw blade and battery a lot quicker than standard plywood, but that probably says more about the glue that was used than the wood. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) in the correct place for the stainless-toughness-edge-retention graphic? Advantages: Toughness, edge retention. 8cr13mov if proper slicing geometry its good budget steel if you dont rust it and no prying or screwing its ok cutting steel. Its probably in between Vanadis 8 and 10V. Both steel types don't chip easily, but 14c28n steel is easier to sharpen. Honestly, yes, because its perfect steel for your knife, besides it depends on which knife, so when youre talking about chef knives, then 14c28n would be an ideal pick thanks to professional corrosion resistance and edge retention. It mainly made for knife and it high in Chromium for excellent corrosion resistance. CPM-REX 121 and Maxamet are both in this category. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% its relatively corrosion-resistant. I dipped each in lemon juice and left in open air and tested after 30, 100, and 300 minutes, dipping in lemon juice again each time. These steels are typically used by forging bladesmiths, traditional folders, and some production fixed blades. . With a high level ofedge retention, corrosion resistance, and toughness, it does most everything quite well. 8am-5pm Saturday. But among the steels youll find at Cabelas and the like, this is a pretty good choice. I forgot, I got the higher carbon steels will have higher edge retention from this website. Get for a complete guide about other steel; you can read 14c28n vs 8cr13mov reviews. Corrosion Resistance: D2 steel has a higher chromium content than 8Cr13MoV, which makes it better at resisting corrosion and wear. GiantMouse Vox/Anso ACE Iona Liner Lock Knife, Muley Freaks Erik Van Woerkom Charged With Felony Possession of Trophy Mule Deer, The Biggest Improvement to My Camp Kitchen Is a Mini Pizza Oven (But Not for Pizza), Propane Traeger, Moosejaw Coolers, Hybrid HOKAs, Adventure Chess, and More Emerging Gear, Avalanche Outside British Columbia Resort Buries 10, Kills 3 Heli-Skiers, Netflix Unveils First Trailer for Tour de France Series. This list is not exhaustive, so check out some of our rating tables for more information on whatever steel youre interested in. grivory When the blade gets messed up I just replace it. Even metallurgists can have a difficult time estimating properties just based on the elements. Steels high in toughness are excellent for knives likely to see hard impacts, like large chopping knives. I was recommended the Rat 1 in D2 and I also found that I really like the design of the Ruike p135 and p128. In this article, we will discuss the characteristics, pros, cons, and differences between 14C28N and D2 knives to help to make the right choice. Its exceedingly tough and relatively hard, but its not stainless. My favorites of the high edge retention group are Vanadis 8 and CPM-10V. Everything you need to know to buy the right knife for the job. The excellent corrosion resistance properties of 14C28N are attributed to the high amounts of chromium in its composition. HA! https://knifesteelnerds.com/2020/05/01/testing-the-edge-retention-of-48-knife-steels/, Unfortunately it all comes down to marketing on everybody involved: Industry, knifemakers, users. How would n680 compare to m690? In other words, Rex 121 would be the most difficult to sharpen and 5160 and 8670 would be the easiest. Some of these steels also have vanadium (CruForgeV) or tungsten (Blue Super, V-Toku2, 1.2519) for increased wear resistance. Monday-Friday When it debuted, Sal Glesser described XHP as a combination of D2s hardness and 440Cs corrosion resistance. As a side note, pure tungsten carbide blades (from brands like Sandrin) can have very high levels of edge retention, but they are not made of steel. 14c28n steel has a high Chromium and Carbon percentage. Its hard enough, tough enough, and stain-resistant enough. D2 has been around for more than 20 years, an eternity in. The sharpening makes the knives easy to maintain because they dull faster and require frequent sharpening. Theres also a line of green triangles a bit below that. It also improves edge retention and strength. Its a very hard steel and is exceptionally difficult to sharpen. AEB-L Hi Larrin Youve occasionally mentioned cryo treatment in your posts, including here with LC200N. 14C28N and D2 knives are affordable high-end knives. In all of the cases above, properties are greatly controlled by carbides. Here, we will discuss edge retention, toughness, ease of sharpening, and corrosion resistance. Chris Reeves version, which is about two points less hard than others, is quite good. 14c28n vs D2 Steel. 14c28n Steel - Is it Good for the knife? (Composition Analysis) Youre right I had to check my spreadsheet. It is an excellent steel that in the right hands has proven to produce high performing blades. For example, increasing edge retention from Z-Tuff to 3V (100 mm in the CATRA test) led to a drop in over 10 ft-lbs, a similar drop is seen by going from 3V to CPM-CruWear. 14c28n vs. D2 Steel D2 is as rigid as 14c28n, thus has almost equal edge retention abilities. Which one is right for you? However, D2 steel has better edge retention, while 14C28N offers a better sharpening experience. But Ive found it lacking in hardness, even when compared to cheaper steels like AUS-8. LC200N Like S90V, its a high-hardness steel, but its more balanced than S90V. YMMV 14C28N VS D2 The two sheets of steel are comparable in terms of toughness and corrosion resistance. As with high alloy tool steels, the amount of vanadium can be a shortcut to predicting the general level of wear resistance and edge retention. Keeping in mind that I have a well rounded Set of sharpening skills. The 1.4116 I tested has large carbides in it which is presumably the reason for low measured toughness: https://knifesteelnerds.com/2019/05/26/new-micrographs-of-42-knife-steels/. D2 steel is a ordinary tool steel and knife steel. So for most steels they are given a rating at around 59-62 Rc, apart from a few steels that are never used at that hardness. AEB-L is rarely found on production knives but can be found on custom knives easily. Spyderco and Cold Steel have used it, though Cold Steel recently switched to S35VN due to availability concerns. CPM154 is a truly superior steel. Also D2 is not stainless as at least 5% of its chromium is tied up in carbides where it doesnt help prevent corrosion. Steel softens as tempering temperature increases, but certain steels see an increase in hardness in a certain higher temperature range such as shown below for high speed steels that are designed for this type of tempering: This high temperature tempering can be done for several reasons, such as better resistance to overheating during grinding, or because a coating will be applied to the knife that requires a high temperature. Corrosion is not only cosmetic. 14C28N is essentially AEB-L (or perhaps more accurately Sandvik 13C26), but with improved corrosion resistance. Some steel companies charge more than others. These steels are the good old hard-working steels. Toughness is the resistance to chipping or breaking. It was originally developed for use as ball-bearing steel by NASA. I think you wrote an article a bit ago on CTS-XHP and concluded that like D2 and ZDP-189 it wasnt really stainless (although stainless is a somewhat arbitrary line). You also reported 8.6 for 440A in that post, compared to 8.5 in this post. ), intended use will give you all the answers. Nitro V is also significantly cheaper than many other steels with this level of performance. What is 14c28n Steel? is it good for knife? (Complete Steel Guide) 14C28N is stainless steel, and its knives offer excellent rust resistance and toughness than D2 steel. 14c28n vs d2 - Which Model For Best - Knifeyellowpages Cool! 14C28N steel, also known as Sandvik 14C28N, is stainless steel made by Sandvik, a European steel company in Sweden. Read more about how it works here. I was the heat treater, but after HT to only 58-59 hardness the blades went to the surface grinders for finishing and I remember them going into the packing boxes with mirror polished edges. So, it is quite harder than most other steel variants and retains its edge sharp for a long period. Developed by New Jersey Steel Baron, Nitro V is a non-powder steel marketed as an enhanced version of AEB-L. Nitro V, as its name indicates, adds nitrogen to AEB-Ls formula to make the steel even more corrosion-resistant. Its an anomaly in the knife world and quite puzzling to use. 1) the cvn number is just that, a number. The 14C28N, on the other hand, is tougher. I was wondering if the 14c28n sample was also prequenched like the AEB-L toughness samples? Heres The Best Review For You (2021), D2 knife blade offers high edge retention, Dulls faster, Requires frequent sharpening. In many cases, the D2 edge sharpness may last a bit longer. Question. Its not bad, but you can find better in the market at the same price. They made planer blades out D2 for its edge retention. The edge retention numbers are normalized to the hardness of the closest toughness test. 0.62% of Carbon: Makes knives harder and more resistant. This doesnt necessarily mean they have terrible toughness, but they have limitations. The steel was developed to be free from chromium carbides which gives it properties similar to balanced non-stainless tool steels like CPM-4V and CPM-CruWear. Is that regression line (or other trend line?) I was just comparing AEB-L and 14c28n to decide which steel to get for my next knife project and although 14c28n seems to be a bit more abrasion resistant, my primary goal is toughness and edge stability. Stainless steels usually top out around 64 Rc and may require careful heat treating to get there. Here, we break down how to choose a flashlight, including best flashlight LEDs, batteries, designs, and more. Most low alloy tool steels and carbon steels also have fine carbide structures without powder metallurgy processing. The difference in properties between 14C28N and D2 steel is very clear. Socould you please clarify which steel is the outlier and which is the line>. A new steel from Crucible, SPY27 launched in 2020 in the Spyderco Native 5and Para 3. Dr. Thomas is a friend of ours here at Blade HQ, and with his help, weve worked to create this knife steel guide. Even premium steels can have poor performance with poor heat treatment. In particular, I really care about the toughness / hardness part. Copper frame are very sturdy and machine well and take the best patina over time. (Some crazy folks clean their Swiss Army knivesin adishwasher. The steel comes with increased wear and abrasion resistance properties. A European powder-metal steel used in higher-end knives, Elmax has an advanced formula, and the result is a very good all-around steel, a generation ahead of formulations like 154CM. Also, if you want a fishing knife, 14c28n steel will survive better in wet areas than D2. This is a bit of a guess because I cant find un-notched Charpy data on it. My other knives are a Real Steel E77 8cr14mov. Im going to give the ratings first and then give more explanation about how the ratings were created. But keep in mind that no steel is perfect for everything. 14C28N is the highest-selling steel of Sandvik, a Swedish steel company. D2 at 58 hard will cut much more rope than AEB-L at 62. The D2 version is heavier and harder, but doesn't cut as smoothly. Vanadium carbides are among the hardest that form in steel, and chromium carbides are in between iron carbide and vanadium carbide. These two knives are a little bit more than a pretty face. Therefore powder metallurgy is not necessary for certain steels, or could even be slightly detrimental. These steels are perfect for thin edges and high hardness. third and most important is what happened to the burr. Privacy Policy. Anybody know how the Sandvik stacks up against all these other steels. And easy to sharpen in our experience; and that will get an excellent razor edge that lasts for a reasonable price of time. compare different heat treats of the same component, it lacks a theoretical foundation and its not clear how to relate it to the real world. in relation to hardness). Who looking for latest, high carbon, then the Kershaw Natrix Copper Pocketknife. thanks thats interesting. does 1.4116 deserve the title of title of ultimate trash steel? This is a non-powder steel produced by American steel company Carpenter. Knife Steel Guide - Knife Life - Blade HQ D2 is carbon steel that has high toughness and durability. Different companies can vary some between each other making the same product, while a single company is going to be more consistent. The majority of knives target 63 Rc or below so this limitation of stainless steels does not always come into play but can be an important factor for certain knives targeting high performance and thin edges. The D2 knife blade offers high edge retention and wear resistance. Its called memory metal because heat can get it to revert back to a previous shape. For example, see the chart below for how much edge retention can change with edge geometry for a single steel (in this case 154CM and CPM-154). 14c28n Steel Is Good for Knife? Here's The Best Review For - Milkwood Ah ok that wasnt mentioned. second it might be of importance which way you sharpened because if against the edge the steels might have reacted differently to the contamination remaining on the edge. I also have a video that summarizes some of the information below while also showing how some of the experiments work. Another is that 8Cr13MoV is a generic name for a specific composition while AUS-8 is a name of a product by a specific company. drop point In my experience, it will tarnish and discolor quickly. 14C28N VS D2 Attributes: 14c28n: D2 . It has a lower hardness and edge retention as compared to the 9Cr knife. This was described in this article on Vanax heat treating. D2 steel is more durable than 14C28N, but it scores lower in terms of ease of sharpening and corrosion resistance. It's like the difference between average 420HC and Buck's 420HC with the Bos heat treatment, only from a better starting point. Aluminum oxide is used in most common sharpening stones and it is softer than vanadium carbide, which makes sharpening high vanadium steels more difficult. Hi Larrin Your estimate of 420HCs corrosion resistance is different here than in your October, 2019 post on corrosion resistance testing: https://knifesteelnerds.com/2019/10/14/corrosion-resistance-testing/ https://knifesteelnerds.com/2018/12/10/cryogenic-processing-of-steel-part-2/ But its lightyears ahead of the alternatives, specifically titanium-bladed knives. 1.4116 got a 2.5 for toughness and edge retention where as 420HC got a 9 for toughness and a 2.5 for edge retention. They lack the carbon necessary to hold an edge, even during mild use. So, its hard steel is easy to sharpen. Steels 7Cr and below arent worth your time or money. I know it's much more stainless and corrosion resisitance, but what about wear resistance? Diamond and CBN stones make sharpening those steels easier. The Kershaw Leek is a most popular EDC knife that design by legendary custom knife maker Ken Onion. This was not necessarily because of superior toughness but because of the superior strength of the MagnaCut from higher hardness. 9Cr18MoV Steel: Full Details and Review - Bud Nealy Knife Maker D2 has a relatively high amount of carbon in its composition (1.55%), more than twice as much as AEB-L (0.68%), but most of that carbon goes into making chromium carbides instead of into solution in the steel matrix, leaving D2 with only ~0.5% C in solution and very large carbides that are good for wear resistance but bad for toughness. This is an old high-carbon (non-stainless) steel. 8Cr13MoV still has some corrosion resistance, but not as much as D2. Vancron would work well in a kitchen knife. 14C28N vs D2: Which Steel Is Better? - Knifeful.com Its hard to say. So what is the best steel for knives? The definition of a quality knife differs among users because of varied needs, but there are basic properties that every quality knife must have. 3) catra is (as far as i know) the only accredited (iso/en) testing method. Having 1.5% Carbon does that. Poor heat treatment can make a knife too hard, too soft, hard to sharpen, easy to deform, or cause other issues. Fine-carbide knife steels. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. You need a hard medium to sharpen it like diamond or boride. The knife Natrix with substantial copper handle is a deceptively hefty EDC. great work, larrin. A Japanese powder steel, ZDP-189 is essentially the polar opposite of 3V its uber-hard instead of uber-tough. 14C28N and D2 steel are not the same. The ratings in this article rate ease of sharpening primarily based on wear resistance, but if a knife is difficult to sharpen, there may be other factors in play. D2/K110 pros/cons in 2020? - Spyderco Forums Hes already done a three part series on cryogenic treatment: This is especially important for chopping knives and for knives with thin edges for enhanced cutting ability and edge retention. Thanks for the Article Larrin, The claim is that they align the blades edge, pushing any slightly rolled over bits back into place and thus preserving the cutting ability of the knife for longer. This showed that XHP and ZDP-189 have significantly lower corrosion resistance than other stainless steels. However, it falls behind the Bohler steel in corrosion resistance. I also have meat cleaver 1,4116 ,58RC that I order and was looking up if its a good steel or did waist money and need to return it. By that I dont mean that a better heat treatment is not possible, but that major mistakes in heat treating are avoided. Low Alloy tool steels have small alloy additions to increase hardenability so they harden more easily in oil rather than water. He is the mind and writer behind Knife Steel Nerds, the go-to source for all knowledge about knife steel. However,M390, CTS-204P, and CPM-20CV are all pretty difficult to resharpen, so maintain that edge!
