Rather than upgrade from D2 to M4 or S30V just drop the angle from 40 degrees to 30 degrees. For these reasons D2 steel is a good for smaller folding knives, but is not ideal for large fixed blades such as dedicated choppers and large survival knives. Its not a particularly great cutter, being poor at retaining an edge. Note that corrosion is detrimental for the cutting edge. In my experience, it will tarnish and discolor quickly. With steels that have a small amount of carbide the size of the carbides can be kept small through processing (see the AEB-L micrograph earlier in the article). Lately Ive been edcing one of those instead of a nice folder. Some of these steels also have vanadium (CruForgeV) or tungsten (Blue Super, V-Toku2, 1.2519) for increased wear resistance. Jesse Jarosz, a custom maker from Montana, regularly uses AEB-L. But yes, I would assume that the general performance would still be relatively similar between them without evidence to the contrary. . Jeff I worked at a company that heat treated D2 (1.55% C) planer blades for a company that built wood working equipment for commercial shops. as you mentioned catra indicates the edge angle as being by far the most important variable. 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. 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. ApexUltra is a steel that we are working on that had excellent properties in small batch production (50 lbs). 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. This does not predict which knife will cut longer or be more resistant to chipping. What it is: D2 is a carbon tool steel with a relatively high chromium content, prompting some to call it a "semi-stainless" steel. 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. That provides 14% Chromium and offers excellent corrosion resistance. Then we could say, e.g. Fine-carbide knife steels. 14C28N is a type of high-performance stainless steel used in knife-making. Often used for combat knives. Thats a pretty large difference in two budget steels that are often compared to each other. EDGE RETENTION . There are a few other complicating factors such as carbon in solution and plate martensite, especially in low alloy steels such as described in this article. If you look at the chart you may notice that at high toughness levels if you increase edge retention by only a relatively small amount you get very big drops in toughness. 14C28N VS S30V S30V steel provides improved corrosion resistance, sharpening ease, and edge retention. Very much appreciate you. FRN Thats a tiny difference, but in combination with the 420HC disparity, it conceals a full point difference between 420HC and 440A: 7.6 vs. 8.6. Thank you. and corrosion resistance than the 420HC steel. My name is Jonathan M, and Im a passionate Mechanical Engineer, a knife enthusiast, and the author of this website. 12C27 8cr13mov if proper slicing geometry its good budget steel if you dont rust it and no prying or screwing its ok cutting steel. The very good toughness of MagnaCut meant that it didnt chip despite this relatively high hardness and the difficulty of the test. Spyderco has produced several production knives with Maxamet, and the steel debuted on the ZT0888. In reality hardly difference. What would you rate the toughness of CPM-D2. 1095. The 14C28N stainless steel from Swedish manufacturer Sandvik is considered an upgrade to their 13C26 steel (described below). Corrosion Resistance: D2 steel has a higher chromium content than 8Cr13MoV, which makes it better at resisting corrosion and wear. 3) catra is (as far as i know) the only accredited (iso/en) testing method. Poor availability may effectively increase cost of steel. Yes its very easy to sharpen but it doesnt hold an edge at all. It mainly made for knife and it high in Chromium for excellent corrosion resistance. You can read about my CATRA edge retention testing in this article. When it comes to handle material, both knives have options available in either plastic or metal. 14C28N knives offer excellent corrosion resistance and toughness. 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. third and most important is what happened to the burr. does 1.4116 deserve the title of title of ultimate trash steel? Read more about how it works here. Looks like there is no reason to us it over 420HC. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% its relatively corrosion-resistant. Steels that can be high in edge retention and toughness are desirable for general use knives. 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. All three of these steels havechromium, molybdenum, vanadium, and tungsten components and will perform well in myriad tasks. Tanto Now that we know what each factor represents, we can see how the steels rank against one another. Why wouldnt it be possible to make a damascus steel out of (say) AEB-L and s90V, or wouldnt that gain the best of both? These steels are the good old hard-working steels. CPM 154 The main downside is the steel is more difficult to heat treat and can't go harder than about 60 or perhaps 61 Rc. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. So the major tradeoff is in how much carbide you want in the steel for edge retention without dropping toughness too much for the intended knife and user. But unlike most high-end steels, SPY27 is an easily user-serviceable powder steel. However, many kinds of wood are REALLY tough and very hard on blades. 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. I made most of my leather knives from O1v (O1 with .20V) that I hold at 1475 for 15 mins and quench in 120-130 F AAA oil and Kevin Cashen is where those parameters came from btw. Toughness and edge retention are generally opposing properties and it is difficult to improve both of them at the same time. Im a layman trying to understand what makes the best steel for my use. in relation to hardness). The highest edge retention steel was Rex 121 which was at 70 Rc in combination with lots of high hardness vanadium carbides. The excellent corrosion resistance properties of 14C28N are attributed to the high amounts of chromium in its composition. Poor heat treatment can make a knife too hard, too soft, hard to sharpen, easy to deform, or cause other issues. 14C28N Hello everyone I've been loking into twosun knives recently. 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. On the spreadsheet, youve grouped AUS-8 and 8Cr13MoV. However, it is not really known how many different companies are making 8Cr13MoV (or at least I dont know), it could be that it is one manufacturer that is dominating the market. 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. https://www.patreon.com/Knifesteelnerds, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). 14c28n vs. D2 Steel D2 is as rigid as 14c28n, thus has almost equal edge retention abilities. Monday-Friday We should be suspicious of anyone who is claiming very high edge retention with a steel at low hardness and a small amount of carbide. Not every wood is soft pine. 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. 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. Lets talk about the clip-on pocket knife. 14C28N and D2 steel are not the same. first there might have been some annealing going on (even if its was a microscopic level) and the steels might have reacted differently. 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.). Larrin, thank you for this. 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. Both steel types don't chip easily, but 14c28n steel is easier to sharpen. The biggest factor for cost of knife steel is whether it is produced with conventional ingot technology or powder metallurgy. D2 is carbon steel that has high toughness and durability. A more obtuse edge angle is much more resistant to chipping than an acute edge. Conventionally produced steels include AEB-L, A2, 52100, 12C27, 14C28N, and AUS-8/,8Cr13MoV. Contact me if you have any questions or input! Most production knives are more than thick enough at the edge to accommodate a regrind to significantly improve performance, and its a lot cheaper than buying a new knife a lot of the time. Many steels are very similar to one another but go by different names from different manufacturers. 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? The 14C28N, on the other hand, is tougher. With a high level ofedge retention, corrosion resistance, and toughness, it does most everything quite well. We did the research to help you find the best hunting knife for your needs and budget. There is buzz out there but I havent seen anything solid yet in the world of steel. CPM 4V High wear resistance steels are more expensive to buy and to process, especially since many require powder metallurgy. Ease of Sharpening: One advantage of 8Cr13MoV is that it is easier to sharpen than D2 steel. I have a (relatively) short introduction before getting into the ratings with a few important things to put them into context. Other factors include how thick your edge is, how dull your knife was at the start, the nature of the heat treatment, and what youre using to sharpen your knife. This is an American-made powder steel produced by Crucible and developed specifically for knives with the aid of the knife guru Chris Reeve (maker of the vaunted Sebenza, among other gems). These are Chinese-produced steels that recently started showing up in Chinese-made knives. This was not necessarily because of superior toughness but because of the superior strength of the MagnaCut from higher hardness. Why do you give a coin with a knife as a gift? The Kershaw Leek is a most popular EDC knife that design by legendary custom knife maker Ken Onion. The both blade are equally wear resistant. The biggest change that is seen with powder metallurgy in measured properties is in regards to toughness. Here, we will discuss edge retention, toughness, ease of sharpening, and corrosion resistance. It improves wear resistance and hardenability. Steels patina in the acid at varying rates which allows for one steel to etch darker than the other and show that famous patterned contrast. Without any confusion, you can purchase this set that has a slim, versatile, modified drip-point blade with good slicing capabilities. There one of the best reason that he is highly regarded as a knife designer. 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. There is a powder form, CPM-D2, and PSF27 is also very chemically similar. 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. Vanax and LC200N are unique in reaching 59-60 Rc while being very stain resistant. It can build a knife that sustains a sharp cutting edge for long periods and is sufficiently wear-resistant. If you need something that soaks up abuse, try 3V. Thats a little too far, but you get the point.). The definition of a quality knife differs among users because of varied needs, but there are basic properties that every quality knife must have. For example, Bohler M390, CTS-204P, and CPM-20CV are all nearly identical and indistinguishable in practice. you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. Spyderco announced Native 5 Salt with magnacut, but I saw test of magnacut with salt water and it grows corrosionso Salt with magnacut could be a flop. XHP is an exceptionally well-balanced steel with excellent all-around attributes. Its probably in between Vanadis 8 and 10V. Working closely with our factory the heat treating of this steel has been perfected resulting in excellent performance for the price. D2 steel is a ordinary tool steel and knife steel. If you want for best steel 14c28n and others steel then you can ready 14c28n vs 420hc review. Some steels are cooked up specifically with this in mind and are very difficult to make rust. AR-RPM9 But keep in mind that no steel is perfect for everything. . I believe they are made of simple carbon steel. There is an acceptable range for every element so this doesnt mean that 1084 will always have exactly 0.84% carbon. 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. If youre looking for all all-around best knife steel, youd be hard-pressed to find one better than Bohler Uddeholm M390. 14C28N VS Steel. For example, below is a video comparing a 1095 ESEE knife at 55-57 Rc and a MagnaCut knife at 62.5 Rc, both with the same edge angle. I like it in the Seki City Spydercos, but I would like to know what ratings you would give it. Find your right answers here! I measured corrosion resistance of a slightly lower carbon 420 here: https://knifesteelnerds.com/2020/03/02/cpm-spy27-experiments-toughness-corrosion-resistance-and-more/. Socould you please clarify which steel is the outlier and which is the line>. A mirror finish is the best at resisting corrosion and a rough finish means rust and corrosion is more likely. The high hardness makes it all but impossible to sharpen and machine. Steels that are improperly heat treated have excess retained austenite which makes them extremely difficult to deburr. Note:There is a powder-metal version called CPM154 thats purer than the non-powder version, making it easier for knifemakers to grind. This guide explains important features to consider when buying a new knife for the outdoors. Kershaw, Spyderco and Schrade are among some of the popular users of this steel.. 14C28N. Hi Larrin Youve occasionally mentioned cryo treatment in your posts, including here with LC200N. 2) you do not go into the sharpening in much detail. 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. Its easy to sharpen. M390 Youre right I had to check my spreadsheet. Vg10 and cpms45vn same toughness at same hardness ? Its a good balance between all three attributes, being relatively hard, tough, and corrosion-resistant. looking at getting a nice larger flipper for a little under 100 AUD. Here is the article by Larrin on 48 steels. grivory It has an HRc over 70, usually even harder than Maxamet. LC200N But SM100 is not widely available, hard to heat treat and grind, and exceptionally expensive. But if when youre searching for tough steel for your outdoor experience camping, or hunting, it would be perfect steel but not the best choice therere other steels with better than toughness that would suit your usage. Hi Jimmie, thanks for your comments. No idea. The D2 knife blade offers high edge retention and wear resistance. 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? It's like the difference between average 420HC and Buck's 420HC with the Bos heat treatment, only from a better starting point. Properties: 14C28N: D2: Edge retention: 4/10: 7/10: Ease of sharpening: 6/10: 3/10: Corrosion resistance: 4/10: 4/10: Toughness: 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. I also added a few more steels in this study. 440C steel 440B I know it's much more stainless and corrosion resisitance, but what about wear resistance? Even though it has very high hardness, its also still decently resistant to corrosion and quite tough.
