Spyderco offers this as the high-end steel for many of its evergreen blades, like the Paramilitary 2, Paramilitary 3, Manix 2, and Native 5. Since the heat treatment is done before you get your knife, and its impossible to tell how good the heat treatment is with your eye, you often must rely on the manufacturers reputation for a good heat treat. I have a question about the chart This is the basis on which I do the ratings rather than a linear scale. Not as tough as the best carbon steels, it's tougher than most . You do not expect the prices to be as low as those of low-end knives, but you will get high performance at affordable prices with either. The sharpening makes the knives easy to maintain because they dull faster and require frequent sharpening. Like S90V, its a high-hardness steel, but its more balanced than S90V. Though technically not a stainless steel due to its composition, in use it performs exactly like one. rust resistance.Best of all most knives made from this steel can be had for well under $75.In my opinion Sandvik 14c28n is a better overall steel than that of Aus8,420hc,or ANY of the . HA! It is an excellent steel that in the right hands has proven to produce high performing blades. Heres a brief description of their impact on the resulting steels properties. This is one of the better steels on the market. 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/. https://cedric-ada-store.creator-spring.com/listing/brickard-heritage-collectionGood gravy its bricky on thingsSubscribe and hit the bell! Vanax gives up some toughness and hardness vs MagnaCut for saltwater levels of corrosion resistance. Rex 121 23.5% vanadium carbide, 4% molybdenum/tungsten carbide (M6C), Conventional Ingot vs Powder Metallurgy Carbide Structure. See the chart below showing 52100 steel that was overaustenitized (unintentionally) by a knifemaker that sent me specimens for toughness testing. If the steel is overheated in austenitizing, very large reductions in toughness are possible. Do honing steels as used on kitchen knives actually do anything useful? Quick-reference guide: Know your knife steels - KnivesShipFree Hi Larrin, thanks so much for writing this blog and putting so much reliable information into such an accessible form. Old time 8670, 5160 (known to ignoramuses as 51shitty) and 52100 are excellent choices and arguably better choices than 80crv2. All Rights Reserved. The Vargo Sobata 398 is unlike any other knife on this list. I have a bachelor's degree in Mechanical engineering with a specialization in material science. I have an article that lists off the major mistakes often made in heat treating. And Ive done a lot of experimental work on knife steels where I feel more confident in my own ratings. Five years ago, S30V had a premium price. The 14C28N, on the other hand, is tougher. Thank you for putting this together, incredibly useful! Now that is power planer blades, but the principle stands, less carbon and alloy isnt the best for wood working and Id use a steel like 26C3 (1.25% C .30%Cr) for my hand tools and temper them to around 62 hard and use the best angle for wood shaving, not the best angle for cutting rope. Its a very hard steel and is exceptionally difficult to sharpen. This is a midprice steel with matching performance. Here, we will discuss edge retention, toughness, ease of sharpening, and corrosion resistance. I was guessing 5.5 based on your rating of CPM-154. 9cr18MOV or D2? | BladeForums.com It is a Sandvik stainless steel that originally developed for razor blades. Anybody know how the Sandvik stacks up against all these other steels. The consent submitted will only be used for data processing originating from this website. 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. how much more can you bend/pry with it? CRKT Bona Fide Review: 1.4116 Steel vs. D2 - Nothing But Knives Some steel companies charge more than others. Its so high in hardness that Maxamet knives usually ship with desiccating packages. Combination of knife steel properties. S110V has improved corrosion resistance at the cost of some toughness compared to S90V. Read about my tests in this article. Poor heat treatment can make a knife too hard, too soft, hard to sharpen, easy to deform, or cause other issues. 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). M390 Because of the material difference, the blades differ in toughness, edge retention, corrosion resistance, and ease of sharpening. . Wusthof Classic Ikon 8-Inch Cooks Knife Review, Victorinox Fibrox Straight Edge Chefs Knife Review, What is Cts bd1 steel? Thats a little too far, but you get the point.). Many steels are very similar to one another but go by different names from different manufacturers. [Steel Knife Review], What is 14c28n steel? Furthermore, because of its ultrahigh hardness, Maxamet is very prone to corrosion, probably worse than 1095. Lets talk about the clip-on pocket knife. Even premium steels can have poor performance with poor heat treatment. My other knives are a Real Steel E77 8cr14mov. And we list budget-friendly knives that have a professional style and grace to them. Cronidur 30 One important concept I want to hammer home is that there isnt one property that is most important. Because of their good edge retention, these steels are quite versatile in folders and fixed blades. Been here before? And only Vanax and LC200N have been free from corrosion with a 3.5% saltwater solution, though MagnaCut was close. But SM100 is not widely available, hard to heat treat and grind, and exceptionally expensive. It doesnt hold an edge well, but its so easy to sharpen that you can get it back to razor sharpness in a few minutes. The high hardness makes it all but impossible to sharpen and machine. This is a virtually stain-proof steel suitable for all sorts of aquatic environments. Spyderco has produced several production knives with Maxamet, and the steel debuted on the ZT0888. A2 is a tool steel renowned for toughness. But yes, I would assume that the general performance would still be relatively similar between them without evidence to the contrary. Metallurgy and Testing of Knives and Steel. Low Alloy tool steels have small alloy additions to increase hardenability so they harden more easily in oil rather than water. Almost all of the knives in my EDC rotation are Spydercos, in exotic steels. It's like the difference between average 420HC and Buck's 420HC with the Bos heat treatment, only from a better starting point. Vancron has a very fine microstructure so it would be tough to beat. Hammering through hickory, digging at roots in sandy soil, and cutting around bone did nothing to chip, dent, or roll the edge of my 3V knives. In many cases the cost of working with the steel for the knife companies is more significant than the cost of the steel itself. Ease of Sharpening: One advantage of 8Cr13MoV is that it is easier to sharpen than D2 steel. Sandvik 14C28N Knife Steel Review: Is This a Good Knife? My test is for comparing different steels, not necessarily for a go/no go test for saltwater applications. Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. 3) catra is (as far as i know) the only accredited (iso/en) testing method. Rather than upgrade from D2 to M4 or S30V just drop the angle from 40 degrees to 30 degrees. Also D2 is not stainless as at least 5% of its chromium is tied up in carbides where it doesnt help prevent corrosion. 14C28N Vs D2 . document.getElementById( "ak_js" ).setAttribute( "value", ( new Date() ).getTime() ); Enter your email address to subscribe to this blog and receive notifications of new posts by email. Become a patron and gain access to awesome rewards including early access to articles or a Knife Steel Nerds mug! However, it falls behind the Bohler steel in corrosion resistance. Almost all consumer-grade pocket knives, EDC knives, fixed blade knives, etc will be in the range of a Rockwell Hardness rating of 54 to 65 HRC. The Sandvik 14c28n steel is ideal for the manufacturing of steel knife blades. How would n680 compare to m690? A hunting knife has a singlepurpose: processing meat after akill. Start comparing steels. Most of these steels are carbon steels, except for CPM MagnaCut (the fancy steel cooked up specifically for knives by Dr. Thomas), which has excellent corrosion resistance. I cant seem to match steel to the SS data points on the toughness/tcc graph. D2 steel, on the other hand, is tool steel, and its knives shine on edge retention and wear resistance. It has excellent edge retention, corrosion resistance, and ease of sharpening. Not impractical fantasy knives, but these two knives that have a col look to them. 2) you do not go into the sharpening in much detail. This steel, as the name implies has a professional styling to it. 14c28n vs. D2 Steel D2 is as rigid as 14c28n, thus has almost equal edge retention abilities. Great for tensile strength and Edge retention. 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. D2 holds it for longer. Hello everyone I've been loking into twosun knives recently. Not every wood is soft pine. 440C steel quite possibly the best steel youll find on a sub-$30 production knife. 14C28N is stainless steel, and its knives offer excellent rust resistance and toughness than D2 steel. I would also suggest adding a hardness rating to the ratings tables that currently include toughness, edge retention, and corrosion resistance ratings. It richly deserves its reputation for high-quality gained over the years by Sandvik, a Swedish manufacturer of world-renowned steel.

Where the black-finished 1.4116 version has a simple, full flat grind, the D2 version has a compound flat grind that ends halfway up the blade's height. My favorites of the high edge retention group are Vanadis 8 and CPM-10V. while its a very intuitive method and a simple way to e.g. D2 is a tool steel used in industrial settings. Hi Larrin Youve occasionally mentioned cryo treatment in your posts, including here with LC200N. nevertheles its importand to keep in mind what exactly is going on there (abrasive plastic media, loss of most of cutting ability during the first few strokes etc.). There you said 7.6 for 420HC. Knife Steel Guide - Knife Life - Blade HQ A2 Knife Steel Air-hardened tool steel. These images are taken from my book Knife Engineering. 14C28N is a type of high-performance stainless steel used in knife-making. There was significant sharpness loss with 1095, almost none with 440A, and D2 was in between. CPM 154 imo o lot depends on how the blade is sharpened. 14C28N steel is known to offer among the best if not the best toughness in knife steels out there. The knife does dull faster. Sandvik 14C28N steel offers excellent corrosion resistance, exceptional toughness, good edge retention, and is easier to sharpen. We have our views as well, and here they are! For example, Bohler M390, CTS-204P, and CPM-20CV are all nearly identical and indistinguishable in practice. Then you can compare 14c28n vs d2, and we hope you will find the right one for your needs. the more complex fracture toughness at least lets you make some estimates in this sence. Powder metallurgy steels with low vanadium content like CPM-1V and Z-Tuff/CD#1 have extremely high toughness. S45VN These steels are perfect for thin edges and high hardness. In particular, I really care about the toughness / hardness part. Not every element is shown in the charts. . FRN The maximum edge retention available in this group is not particularly high because most of the wear resistance comes from iron carbide, also called cementite, which is the softest of the different carbide types. How could it be? . The steel is susceptible to overheating during hardening do not overheat. 1095 stains easily and thus is often coated, especially in fixed blades. What it is: 14C28N is a Sandvik stainless steel commonly used in razors and kitchen knives. 14C28N and D2 steel are not the same. These steels are typically used by forging bladesmiths, traditional folders, and some production fixed blades. You can read about my CATRA edge retention testing in this article. Its very similar chemically to RWL 34 and ATS-34. When it comes to handle material, both knives have options available in either plastic or metal. Its exceedingly tough and relatively hard, but its not stainless. There are so many interactions between them that predictions are difficult without modeling software. Steels like CPM MagnaCut, CPM M4, CPM 4V, and CPM CruWear fit in this category. But Ive found it lacking in hardness, even when compared to cheaper steels like AUS-8. That says to me theres a measurable abrasive quality to wood for sure. Youre right I had to check my spreadsheet. Quite an eyeopener! You can read an article I wrote on budget steels here. In this article, we will discuss the characteristics, pros, cons, and differences between 14C28N and D2 knives to help to make the right choice. I also added a few more steels in this study. It is most useful for steels with large amounts of carbide but also helps to be able to add certain carbide types. Different companies can vary some between each other making the same product, while a single company is going to be more consistent. I see very little about cryo outside of journal articles, and I wonder which knifemakers use it. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. Coarse-carbide tool steel grades. I did a test with knives in 440A (stainless), D2 (high alloy steel with some corrosion resistance), and 1095 (no corrosion resistance). What it is: D2 is a carbon tool steel with a relatively high chromium content, prompting some to call it a "semi-stainless" steel. But then if you look at an increase of 100 mm in the CATRA test from Maxamet to Rex 121 the toughness only drops 1-2 ft-lbs. No idea. Micarta It has enough water-fighting properties that it can be used in marine environments. Now 14c28n is IMO the best budget steel out there. Steels with very high vanadium content like Vanadis 8, CPM-10V, K390, CPM-15V, etc. BD1 is excellent budget steel, very similar in composition and performance to GIN-1, a Japanese steel used a decade ago by Spyderco. Also I notice 1095 looks like another underperformer as there doesnt look to be any reason to use it over 5160 which I cant imagine is any more expensive than 1095. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) For high wear resistance and edge retention you want a large amount of hard carbides. 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. D2 knives, on the other hand, are challenging to sharpen. Many steel ratings seem to over-emphasize edge retention. The both blade are equally wear resistant. 14C28N Steel Review: What To Expect From This Popular Steel? - We Knives Why does Maxamet and Rex 121 stay the same tcc but Zmax drops and 15v goes from below 900 to over? Note that corrosion is detrimental for the cutting edge. I have not provided a rating for ease in sharpening. Therefore, you cannot purchase the knife for use in corrosive environments. 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. Corrosion is not just about cosmetics and rusting, however, but can also affect edge performance. A good quality knife must have sharpness, great edge retention, and a sturdy handle. This showed that XHP and ZDP-189 have significantly lower corrosion resistance than other stainless steels. I did a large study of different knives with identical sharpening and edge geometry. 12C27 steel is extremely popular in the US knife market for its high hardness, high wear resistance, and great corrosion resistance. That is an air-hardening- high carbon, high chromium tool steel. Maxamets hardness results in incredible edge retention and a nightmarish sharpening and machining experience. Like 154CM, there is a newer version, S35VN, which shares many of the same attributes as S30V but is easier to craft into a knife thanks to niobium. In fact Id be delighted to have your experience checking my thinking! And steels with at least 10% chromium are probably stainless, except for several important exceptions like D2 and ZDP-189. Steel is a combination of iron and carbon with other elements. They have many similarities, including their high hardness, strength, and wear resistance. Privacy Policy. After the steel is quenched it is reheated to a lower temperature to increase toughness and decrease hardness. n690 Vanadium carbides are very large with conventional production of steels but are very small with powder metallurgy. AEB-L is rarely found on production knives but can be found on custom knives easily. Diamond and CBN stones make sharpening those steels easier. LC 200N is an elite performer, with high hardness, high toughness, and off-the-charts corrosion resistance. Thank you for the accurate data. MagnaCut If the properties of a knife meet your knife needs and it has the above characteristics, then it qualifies as a quality knife. https://i0.wp.com/knifesteelnerds.com/wp-content/uploads/2021/10/stainless-toughness-10-19-21.jpg?w=757&ssl=1 Could you please compare it to Shirogami #1 and Agomi #1, I didnt find anything in terms of grain size ragarding thoese steels on the Internert. Bohler N690Co Stainless Steel: Is N690 a Good Knife Steel? - KnifeGuides What is pulling that line high and to the right? Im a layman trying to understand what makes the best steel for my use. If youre looking for all all-around best knife steel, youd be hard-pressed to find one better than Bohler Uddeholm M390. Its an update of its 12C27 and 13C26 steels, which were developed for use in shaving razors. 14C28N is the highest-selling steel of Sandvik, a Swedish steel company. So we get back to my original question: if a D2 planer blade at 58 Rc and the associated level of toughness will perform acceptably with a 30 sharpening angle, is there some way to extrapolate at what sharpening angle another steel with higher toughness might perform equally well? 2. I have two quick questions, The hardness of the carbides does not matter much unlike with edge retention.
