14c28n steel vs d2
Thank you for putting this together, incredibly useful! Working closely with our factory the heat treating of this steel has been perfected resulting in excellent performance for the price. We did the research to help you find the best hunting knife for your needs and budget. Another common heat treating choice that is not even categorized as a mistake is tempering in the high temperature regime (~1000F) rather than the low temperature regime (~400F). Uddeholm lists it as somewhat worse in toughness than A2 but somewhat better in wear resistance. just recently the idea occured tome to sharpen a planer blade like a knife and check out how it performs. But Ive found it lacking in hardness, even when compared to cheaper steels like AUS-8. There are also hardness/toughness and hardness/TCC charts.but no tables backing this charts. There seem to be a lot of modern steels that get related to D2, but OTOH just saying a steel is similar to D2 seems to kill interest in it. The material increase machinability and strength. a burr might have developped on some of the steels and not on others, it might have ben reduced or even removed by the process.

Knife steel nerds have a great write up on 14c28n nik_was 2 yr. ago The Sandvik 14C28N has a very thin and sharp blade that is perfect for slicing through things. When it comes to handle material, both knives have options available in either plastic or metal. In reality hardly difference. That is an air-hardening- high carbon, high chromium tool steel. You cant look at only the chromium content of the steel to know the level of 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. 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. Let the job at hand be your guide. I wont go into detail about those here. And before you start arguing on behalf of the steel you think might be perfect, let me remind you that if your knife isnt perfect for a task, youll need to get another one that is! 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. 14C28N steel is known to offer the highest toughness levels out there. Im not sure they answer my question, though, and some of your points dont seem to jive with the info here on Larrins site. They were two different tests (different batch of steel, different person heat treating, etc). It can withstand a lot of wear and tear. 2. . Cronidur 30 I have a Spyderco K390 knife and I cut leather with it as it is only .090 thick and I seldom have to strop it on 1 micron diamond compound on leather. 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. When we plot toughness vs edge retention on a log scale instead we get a straight line that is a better visualization of toughness differences. S35VN Hes already done a three part series on cryogenic treatment: We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development. Different heat treats have emerged over the years, but one has risen to the top as the best:Bob Doziers D2. Without any confusion, you can purchase this set that has a slim, versatile, modified drip-point blade with good slicing capabilities. There are a few aspects to your question, I think. Ive not seen these used on non-kitchen knives, though, and it seems that if they had real utility they would be used in other knives as well although perhaps on the thinner edges of kitchen knives they are more effective than they would be elsewhere? This does not predict which knife will cut longer or be more resistant to chipping. 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 main downside is the steel is more difficult to heat treat and cant go harder than about 60 or perhaps 61 Rc. You said wood is not a particularly abrasive material and in absolute terms that is very true. These steels have sufficient toughness to handle thinner edge geometry. This is about comparing steels to each other rather than a limitation of an individual steel. HA! H1 and 420 also have excellent corrosion resistance but are limited to lower hardness and edge retention. On the other hand, 9cr18mov has a slightly higher molybdenum content which gives it higher hardness from quenching and helps drive carbide formation. can you strike twice as fast with the knife? In general, the more carbide the steel has and the larger the carbides the lower is the toughness. 14c28n vs. D2 Steel D2 is as rigid as 14c28n, thus has almost equal edge retention abilities. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. Importing steel from Europe to the USA, or vice versa, generally increases the cost. My other knives are a Real Steel E77 8cr14mov. 14C28N steel is as a result of a more corrosion resistant version of the 13C26 steel. INFI is also quite hard and sharpens easily. But weve tested this metal in the form of the Sobata 398 for nearly a year and have been continually impressed. Thanks to its very high hardness (64-66 HRc compared to the average of 58-62 HRc), ZDP-189 can be ground thinner and sharpened less often. A2 knives need care taken to avoid rust and are often coated to inhibit corrosion. Most of these steels rely on particle metallurgy and are therefore more expensive. I wrote an article about knife steel ratings available online in 2018, where I concluded that none of them were very good. Damascus or pattern welded steel is a result of combining two steels together. Time and use have proven this to be quite accurate. D2 steel also resists chipping better than most stainless steel types. 1.4116 The bump in hardness comes from precipitation of fine carbides in the steel, read an article I wrote on budget steels here, https://knifesteelnerds.com/2019/05/26/new-micrographs-of-42-knife-steels/, https://i0.wp.com/knifesteelnerds.com/wp-content/uploads/2021/10/stainless-toughness-10-19-21.jpg?w=757&ssl=1, https://knifesteelnerds.com/2019/10/14/corrosion-resistance-testing/, https://knifesteelnerds.com/2020/03/02/cpm-spy27-experiments-toughness-corrosion-resistance-and-more/, https://knifesteelnerds.com/2018/12/03/cryogenic-part1/, https://knifesteelnerds.com/2018/12/10/cryogenic-processing-of-steel-part-2/, https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/, The Pros And Cons Of Stainless Steel Copper And Aluminum Brewing Equipment SanctuaryBrewCo, https://knifesteelnerds.com/2020/05/01/testing-the-edge-retention-of-48-knife-steels/. The steel falls under the Sandvik series of steels and makes one of the 7 steel grades in this family including 12C27M, 14C28N, 13C26, and others. The ratings I have are for an optimal heat treatment. Now 14c28n is IMO the best budget steel out there. Sign up to receive GearJunkie content direct to your inbox. Not impractical fantasy knives, but these two knives that have a col look to them. GearJunkie Copyright 2013 2023. 14C28N knives will handle challenging and demanding applications without chipping, cracking, or breaking. I have not provided a rating for ease in sharpening. That says to me theres a measurable abrasive quality to wood for sure. This doesnt necessarily mean they have terrible toughness, but they have limitations. great work, larrin. 14C28N VS S30V S30V steel provides improved corrosion resistance, sharpening ease, and edge retention. The knives can be used in humid and wet environments without rusting. But SM100 is not widely available, hard to heat treat and grind, and exceptionally expensive. 14C28N steel holds good hardness. This showed that XHP and ZDP-189 have significantly lower corrosion resistance than other stainless steels. The big difference in properties vs the low alloy steels, however, are the harder carbides that are found in these steels. I know that one does not normally make knife blades of titanium, but I gather that Ti is extremely corrosion resistant, used for saltwater applications, etc. 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? You will get an ultra-sharp edge with 14C28N knives. Vanadium carbides are very large with conventional production of steels but are very small with powder metallurgy. Cold Steel still uses VG-1 on some knives, and, for the money, it does well. Steels without these attributes are much less costly. 14C28N knife will dull faster, but it is easy to sharpen. looking at getting a nice larger flipper for a little under 100 AUD. Which knife for best? Should have a first draft by the end of next week. But its very cheap, and, when ground appropriately, it can be a real winner from a value standpoint. Is that accurate? 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.). Extra kudos for your mathmatical steel composition to edge holding model thats really impressive work. This makes it a great choice if you don't have . D2 steel knives, on the other hand, offer great edge retention and wear resistance, which are properties of tool steels.14C28ND2Toughness93.5Edge retention35Corrosion resistance8.54.5Ease of sharpeningEasyModerately Hard14C28N vs D2. It mainly made for knife and it high in Chromium for excellent corrosion resistance. High wear resistance is not particularly necessary when only performing chopping, and its good ease in sharpening helps when having to restore the edges. I guess the question is whether toughness increases faster than edge retention decreases. I would love to see a Tungsten-Carbide blade (like Sandrin is using) and how it compares for Edge Retention, Toughness and Corrosion Resistance especially how it compares to s90v. Corrosion is not just about cosmetics and rusting, however, but can also affect edge performance. Notice that with the same edges on the same media, the 9Cr18Mov from Real Steel performs about as well as the average Chinese D2. Having 1.5% Carbon does that. It would be interesting to try to develop a conversation between /geometry/edge retention/toughness, so we could say e.g. 420 Simple, non-stainless steels of medium carbon content like 5160 also boast high toughness. CROMOVA and yet millons of knives are being made out of 1.4116 (aisi 420mov?) Read more. On the flip side D2 steel is much harder than other steels in this category such as 154CM or ATS-34 and as a result holds its edge a little better. And a label: AEB-L. I was recommended the Rat 1 in D2 and I also found that I really like the design of the Ruike p135 and p128. The Vargo Sobata 398 is unlike any other knife on this list. Although it should be noted that there doesnt seem to be a need for the stainlessness on a wood working tool. 8cr13mov if proper slicing geometry its good budget steel if you dont rust it and no prying or screwing its ok cutting steel. However, the 14c28n provides perfect edge retention with a maximum hardness of 62Hrc and the mixture of Chromium and Carbon. Steels do come at various price points, however, depending on the cost of producing them and the cost for the knife company to work with them. worldwide, even the chinese have an equivalent (8cr13mov). ApexUltra is a steel that we are working on that had excellent properties in small batch production (50 lbs). Or, is this perhaps a historically useful practice that made sense on softer/less tough steels, but would make less sense on some newer steels that can be used at higher hardness and thus higher edge stability? I have two quick questions, The best scenario is when the steel, heat treatment, and geometry are selected for the knife and the use. High Speed steels are a subset that have significant additions of Mo and/or W that makes them resist softening when they are used for machining operations. Conventionally produced steels include AEB-L, A2, 52100, 12C27, 14C28N, and AUS-8/,8Cr13MoV. My favorites of the high edge retention group are Vanadis 8 and CPM-10V. Its not a particularly great cutter, being poor at retaining an edge. Dr. Thomas is a friend of ours here at Blade HQ, and with his help, weve worked to create this knife steel guide. worldwide, even the chinese have an equivalent (8cr13mov). Distilled water can separate steels that are stainless vs those that are not. In other words, heat treating a steel to its maximum hardness does not necessarily mean reduced corrosion resistance. Even it enhances corrosion resistance and wear resistance. We can predict edge retention of a steel within a relatively narrow band based on hardness and carbide volume. 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. The hardness level of steel is determined using a universal scale called the "Rockwell C Test", commonly called the Rockwell hardness scale (HRC). D2 steel is high carbon steel with no extra addition of Cr or Mo, that's why it is prone to corrosion. Tanto The Kershaw Leek is a most popular EDC knife that design by legendary custom knife maker Ken Onion. thanks thats interesting. It is most useful for steels with large amounts of carbide but also helps to be able to add certain carbide types. The high hardness makes it all but impossible to sharpen and machine. D2 is not a bad steel, but it has been around a long time and is somewhat mundane by current standards. While 9Cr18MoV steel is highly corrosion resistant due to the addition of Cr, and Mo. In real life, would you expect any presumed increase in deviation from the specified formula, as well as the effects of said deviation, to negatively impact the performance of 8Cr13MoV to any truly noticeable degree? If the steel is overheated in austenitizing, very large reductions in toughness are possible. So, it is quite harder than most other steel variants and retains its edge sharp for a long period. These steels are typically used by forging bladesmiths, traditional folders, and some production fixed blades. A mirror finish is the best at resisting corrosion and a rough finish means rust and corrosion is more likely. D2 steel Its very corrosion-resistant and quite tough. It boasts an incredible ability to continue cutting long after it seems dull. And its not made of steel. Required fields are marked *. This is to keep the focus on the elements that are making the biggest difference. Steels that can be high in edge retention and toughness are desirable for general use knives. And Mn and Si isnt shown at all for the high alloy steels, even though those elements are added to all of them. D2 holds it for longer. Steel with high wear resistance is more costly to manufacture, as the knife company goes through more abrasives to grind the knives. Or even a 7 in both categories. Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. We use a subsize, unnotched chapy test with 2.5 x 10 x 55 mm dimensions.
