Is this at the same hardness? The vivid patterns visible in Damascus steel come from the acid etching process in a ferric chloride solution. A cryo treatment and close temperature control is necessary to achieve those hardness levels. Only a few years ago Elmax was pricey, but competition has driven it down to reasonable levels, making it a decent value. The best steels with balanced properties include 4V/Vanadis4E, CPM-CruWear, and CPM-M4. Instead, Vargo titanium uses a unique material called sintered titanium-ceramic alloy. This can turn the ultra corrosion resistant LC200N or Vanax into a normal stainless steel that will rust with only 1% saltwater. If you want to learn more about a specific steel, you can click it in the sorted listings below. A2 knives need care taken to avoid rust and are often coated to inhibit corrosion. 14C28N steel is the improved version of 13C26 with better rust resistance. I personally don`t care about stainless (sic! Therefore you will use it for a long time without requiring frequent sharpening. Because of its abrasion-eating hardness, knives with REX 121 come at an exceptionally high price. its like with cars, most of them are not a corvette or a porsche. [Complete Steel Guide], What is Vg-10 steel?- [Steel Knife Review], The Difference Between 440c steel vs d2: Compared guide, Is 8cr13mov Good Knife Steel [Complete Steel Guide], Amazon Best Sellers in Pocket Knives & Folding Knives. Copper frame are very sturdy and machine well and take the best patina over time. It is a Sandvik stainless steel that originally developed for razor blades. I hope you will find value in the articles on this website. : 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. the problem is in the innumerable combinations of grades, grains sizes and coatings available. These properties make steel a good choice for making kitchen, fishing, and everyday knives. Sandvik later came out with 14C28N which is a slightly improved version of 13C26. This doesnt necessarily mean they have terrible toughness, but they have limitations. Here, we will discuss edge retention, toughness, ease of sharpening, and corrosion resistance. It is an excellent steel that in the right hands has proven to produce high performing blades. I especially appreciate the geometry/edge retention/toughness comparison with photos. A2 is a tool steel renowned for toughness. What is pulling that line high and to the right? Sandvik 14C28N Vs D2 Knife - edcTopic.com MC66 Steels without these attributes are much less costly. 14C28N is thus ideal for use in corrosive environments and challenging applications. Steel ratings are not about ranking steels in terms of what is better than another, but understanding the different balances such as toughness vs edge retention. Is there some way we might predict the relative "effective toughness" of different steels at different hardness and at different edge angles? The Vargo Sobata 398 is unlike any other knife on this list. The D2 steel compares nicely with 14c28n steel in terms of edge retention, as it's quite hard as well. we dont know. The Sandvik 14c28n steel is ideal for the manufacturing of steel knife blades. Does that mean that companies like Tops, Kabar and ESEE would be better off using 420HC instead of 1095 on their fixed blades? However, the 14c28n provides perfect edge retention with a maximum hardness of 62Hrc and the mixture of Chromium and Carbon. For more information see our. How would n680 compare to m690? For this perfect size that for most tasks and the slim tip allows the knife to excel at piercing and detail work. Stainless steels usually top out around 64 Rc and may require careful heat treating to get there. If you are looking for a high-end knife on a budget, the varieties of both steel will serve you. However, in our testing there is a reduction in toughness by using the high temperature range rather than the low temperature range, such as was found with CPM-CruWear (Z-Wear) or CPM-10V. With conventional steels this limited vanadium additions to about 4-5%, and this was greatly expanded when powder metallurgy was developed. 440A has more chromium in solution along with a small addition of Mo, but has significant amounts of carbide so the two are an interesting comparison. But a few overly vocal forgers were making claims about it that clearly were not true especially when comparing it to 5160. 14c28n | Civivi 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. Because of the material difference, the blades differ in toughness, edge retention, corrosion resistance, and ease of sharpening. I know it's much more stainless and corrosion resisitance, but what about wear resistance? Cronidur 30 In many cases, the D2 edge sharpness may last a bit longer. However, it can be somewhat complicated because an edge can dull from many causes wear, micro-chipping, deformation, or corrosion. 12C27 steel is extremely popular in the US knife market for its high hardness, high wear resistance, and great corrosion resistance. Custom maker Brian Trudeau uses Nitro V, and Massdrops Perpetua design is the first production knife to sport it. Lets talk about the clip-on pocket knife. Finally, in this 14c28n vs d2, we hope you get the right one. Both knives come at an affordable price for high-end knives. Corrosion on knife steels most usually takes the form of rust, patina, and staining. Start comparing steels. On the other hand, 9cr18mov has a slightly higher molybdenum content which gives it higher hardness from quenching and helps drive carbide formation. . Maxamet is one of two current high-hardness kings, with HRc marks in the high 60s approaching 70, a hardness usually only seen in carbide steels. I actually dont recommend that enthusiasts spend all that much time analyzing the exact composition of different steels and trying to guess their properties. Each of these contributes to a knifes overall performance. 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. Ive found S35VN less chippy even at the same hardness. And Ive done a lot of experimental work on knife steels where I feel more confident in my own ratings. 14C28N vs D2: Which Steel Is Better? - Knifeful.com To choose the best knife for you between the 14C28N and the D2, look at the steel properties and ensure that they suit your knife needs and lifestyle. D2 steel also resists chipping better than most stainless steel types. Steels with very high vanadium content like Vanadis 8, CPM-10V, K390, CPM-15V, etc. at least it has some vanadium over the 420hc. Vancron would work well in a kitchen knife. Thank you for the accurate data. Knifemakers use dozens of steel types to create knife blades. European steel company Sandvik produces 14C28N, a non-powder metallurgy steel. Rust Test includes:D2 from Bestech and WE1095 from shop8Cr13Mov from Spyderco420HC from BuckWalmart knifeY Start (Marked D2)Follow me at:Twitter: https://twi. Not every wood is soft pine. In general, higher carbon and higher vanadium steels have higher wear resistance and edge retention but lower toughness. 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. Using 10 dps sharpening (20 degrees inclusive on the chart) leads to about 5x the edge retention of 25 dps. Kershaw, Spyderco and Schrade are among some of the popular users of this steel.. 14C28N. The best scenario is when the steel, heat treatment, and geometry are selected for the knife and the use. Its soft, with very low carbon content. Dr. Thomas you spoke of using a different media for cutting test and I have some extra veg tan leather and was wondering what are the parameters of the leather you need? This is a midprice steel with matching performance. Not as tough as the best carbon steels, it's tougher than most . 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). In addition, According to Sandvik, 14C28N steel is easy to work on, reducing production costs and hence affordable knives. 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). Not impractical fantasy knives, but these two knives that have a col look to them. That way you can get into the steel ratings quickly. vanax The big difference in properties vs the low alloy steels, however, are the harder carbides that are found in these steels. How long sharpen? Different heat treats have emerged over the years, but one has risen to the top as the best:Bob Doziers D2. A Japanese powder steel, ZDP-189 is essentially the polar opposite of 3V its uber-hard instead of uber-tough. It would be great if you wrote a basic rundown of cryo treatment of knife steels, whats involved, the effects, interactions with other treatments like tempers, alloys that benefit the most, etc. S110V has improved corrosion resistance at the cost of some toughness compared to S90V. D2 has been around for more than 20 years, an eternity in. Im not sure they answer my question, though, and some of your points dont seem to jive with the info here on Larrins site. The Best D2 Steel Knives And What Makes Them Great But if you want to know what the coolest blade material is, for my money, SM100is it. The heat treatment techniques used by the manufacturer as well as the design of the blade itself play a huge role in the ultimate outcome of knife performance! Thanks to Bill Smutz, Alex Topfer, Florian Bachler, Brunhard, Art, Rod H, Sach, Jinny Koh, Jon Duda, Cory Henderson, and UPKnife for becoming Knife Steeel Nerds Patreon supporters! Choose a factor below to start sorting. I will be focusing on CATRA edge retention which measures abrasive wear of knives. The ultra high corrosion resistance steels Vanax or LC200N max out around 60-61 Rc instead. 14C28N vs D2 - knifebasics.com Steels that are improperly heat treated have excess retained austenite which makes them extremely difficult to deburr. 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. For instance, if a 35 edge in 1095 steel at 58 Rc provides appropriate toughness for planing hardwood, what edge angle in, say, AEB-L at 62 Rc might give us a comparable effective toughness? For more information, please see our Note:Dont bother with anything less than 8Cr in this series. However,M390, CTS-204P, and CPM-20CV are all pretty difficult to resharpen, so maintain that edge! Toughness is a measure of how much resistance a steel has to fracturing. Or even if they try to be more open to importance of toughness, the good reputation of the high edge retention steels means that they get inflated toughness ratings along with it. 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. Actually, Id be thinking 14C28N, but I want to leave stainless out. CPM 4V Lots of information is still specific to this article, however. 14C28N and D2 knives are affordable high-end knives. Steels that can be high in edge retention and toughness are desirable for general use knives. There is no such thing as a steel that is a 10 in both toughness and edge retention. Typically an increase in corrosion resistance means a reduction in potential hardness for a given steel. They tend to be relatively expensive and difficult to sharpen, as they have high wear resistance. Generally this is code for difficulty in abrading away steel. A hunting knife has a singlepurpose: processing meat after akill. This list is not exhaustive, so check out some of our rating tables for more information on whatever steel youre interested in. This is a non-powder Japanese steel used primarily in Spyderco knives. See the chart below showing 52100 steel that was overaustenitized (unintentionally) by a knifemaker that sent me specimens for toughness testing. Approximately the same hardness, yes. I have a question about the chart I was recommended the Rat 1 in D2 and I also found that I really like the design of the Ruike p135 and p128. Below shows approximate maximum hardness vs stainless rating for several stainless knife steels. S35VN Even though it has very high hardness, its also still decently resistant to corrosion and quite tough. Coarse-carbide tool steel grades. Divers, sailors, and anglers need knives that will resist corrosion above all else. [Steel Knife Review], Best survival knife sword: 5160 steel Review, What is VG 10 pocket knife? and corrosion resistance than the 420HC steel. 14C28N knives offer better toughness than D2 knives. Each test is done with 3 or more specimens to get a good average. While 14C28N and D2 are both pretty to look at, buyers always regard one over the other. I would think that the label applies to either the line or the outlier, but probably not both unless the outlier is a measurement error. Note:There is a powder-metal version called CPM154 thats purer than the non-powder version, making it easier for knifemakers to grind. 14C28N vs. D2. Both steel types don't chip easily, but 14c28n steel is easier to sharpen. D2 Steel Vs S30v: Which Of These Steels Is Better For Knives? Its not a regression line, it is just a line through the best steels. Ease of Sharpening: One advantage of 8Cr13MoV is that it is easier to sharpen than D2 steel. Recommendations are welcome, If you are cutting against metal I would maybe try K390 in a Spyderco or an S110V knife if you need stainless.

These steels are perfect for thin edges and high hardness. 14c28n vs. AUS-8 Steel The hardness level of steel is determined using a universal scale called the "Rockwell C Test", commonly called the Rockwell hardness scale (HRC). 14C28N knives offer excellent corrosion resistance and toughness. quite possibly the best steel youll find on a sub-$30 production knife. 1) the cvn number is just that, a number. But in my experience, it has been nothing but great. Toughness and edge retention are generally opposing properties and it is difficult to improve both of them at the same time. The main downside is the steel is more difficult to heat treat and cant go harder than about 60 or perhaps 61 Rc. 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. However the 14c28n steel would be great for an EDC knife with typical usage. Which one is right for you? Also D2 is not stainless as at least 5% of its chromium is tied up in carbides where it doesnt help prevent corrosion. Bohler N690Co Stainless Steel: Is N690 a Good Knife Steel? - KnifeGuides This is to keep the focus on the elements that are making the biggest difference. Though the volume of carbonitrides in the steel is relatively high. D2 steel offers better edge retention and wear resistance than 14C28N. CPM-REX 121 and Maxamet are both in this category. 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. 1.4116 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. On the other hand, these types of steel provide high wear resistance and toughness. SPY27 Around 61 Rc usually. 14C28N vs. D2. There was significant sharpness loss with 1095, almost none with 440A, and D2 was in between. Here, read on for an in-depth look at common knife steels as well as the best knife steels around. The pictures below show the microstructures of the three classes of stainless steel on the market. The edge retention and ease of sharpening have been what we expect with D2. 9cr18MOV or D2? | BladeForums.com These steels favor edge retention over all else. CPM 154 Most of the user loves this one that has received a lot of attention on this site. It is certainly possible for a knifemaker or heat treating company to do a heat treatment that will have suboptimal properties. 14C28N, designed by Sandvik at Kershaw's behest to have the edge properties of 13C26 but with increased corrosion resistance by adding nitrogen and chromium. He is the mind and writer behind Knife Steel Nerds, the go-to source for all knowledge about knife steel. Yes its very easy to sharpen but it doesnt hold an edge at all. The 25 dps sharpened knife saw almost no edge damage with 2 ft-lbs while a 15 dps edge saw a significant chip with only 0.3 ft-lbs and catastrophic chipping with 1.4 ft-lbs. Tougher than D2, but less wear-resistant. When the blade gets messed up I just replace it. 14C28N Leek: D2 Leek: jonnymac44 Joined Sep 27, 2007 Messages 7,674 Oct 21, 2008 #2 Hey Michael, First off, the new 14C28N from Sandvik is just now hitting the streets, and I don't have any results just yet for you. Rex 45 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. Below shows Vanax tempered at 400F on the left and 1000F on the right after 1% saltwater for 24 hours: There are many other ways in which knife steel performance can be reduced through heat treatment but I cant cover them all in this article so hopefully these illustrative examples will be enough. Thats a little too far, but you get the point.). Note just because a blade is made from the premium or high-end steels listed above does not automatically mean its better than the lesser steels. 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. Despite its wonderful performance, XHP is actually not terribly expensive compared to other high-end, all-around performers. If thats true why do you include it in the stainless steel category? Corrosion is not only cosmetic. Ive found that most makers harden S30V too much, making it prone to chipping at the edge. 14c28n vs d2 : r/chineseknives - reddit In use, its very similar to 440C and VG-10. If youre having trouble finding the steel you want, see if another manufacturer makes something much like it. This was described in this article on Vanax heat treating. 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. 440A My test is for comparing different steels, not necessarily for a go/no go test for saltwater applications. The brand Bark River uses A2 in many models. What is the Best Budget Knife Steel? - Knife Steel Nerds How Is 14C28N Steel for Knives? All of the experiments shown below are possible thanks to supporters. VG-10 steel also has the same level of toughness as 14C28N and the same level of corrosion resistance. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% its relatively corrosion-resistant. Hello LARRIN, do you have a Rough estimate on when ApexUltra (as well as more Magnacut) will become available? Its not bad, but you can find better in the market at the same price. 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(%). Having 1.5% Carbon does that. (I think the 420HC estimate in that post was based on simulation or computer modeling, since you didnt spray testing any of the 400 series.) I have two quick questions, It's like the difference between average 420HC and Buck's 420HC with the Bos heat treatment, only from a better starting point. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. The critical difference between these two sheets of steel is their corrosion resistance.
