14c28n steel vs d2signs my husband likes my sister

Im writing a book about choosing a knife for EDC. How would n680 compare to m690? In fact Id be delighted to have your experience checking my thinking! The choice between the two depends on your knife needs. 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. 14c28n vs D2 Steel. Steels like CPM MagnaCut, CPM M4, CPM 4V, and CPM CruWear fit in this category. Its a costly and challenging process, but it makes extremely fine-grained steels, some of the best for knives, and makes some processes that were previously impossible a reality. So, its hard steel is easy to sharpen. That way you can get into the steel ratings quickly. If you shop for knives based strictly on steel, you might be disappointed. The difference in properties between 14C28N and D2 steel is very clear. HA! I also added a few more steels in this study. Steels high in toughness are excellent for knives likely to see hard impacts, like large chopping knives. In particular, I really care about the toughness / hardness part. But SM100 is not widely available, hard to heat treat and grind, and exceptionally expensive. vanax Like S90V, its a high-hardness steel, but its more balanced than S90V. This is a powder steel produced by American steel company Carpenter. The hardness of the carbides does not matter much unlike with edge retention. In general, steels look worse as you go up in hardness because the toughness is reduced by more than the edge retention is increased. Sandvik 14C28N steel offers excellent corrosion resistance, exceptional toughness, good edge retention, and is easier to sharpen. worldwide, even the chinese have an equivalent (8cr13mov). 440B 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. Note:Dont bother with anything less than 8Cr in this series. have extremely high edge retention. So presumably, wear resistance would be in the 3.5-4 range and toughness in the 5.5-6 range. In use, its very similar to 440C and VG-10. Is 440A really that much better than 420HC, or have you found a narrower gap? If you want to learn more than keep reading past the ratings. Below shows the results of MagnaCut testing vs other steels where it is labeled as New Steel.. Interesting. 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. The 14C28N stainless steel from Swedish manufacturer Sandvik is considered an upgrade to their 13C26 steel (described below). rex 121 Oftentimes steels that are reported to be difficult to sharpen are in fact improperly heat treated and challenging to deburr. Corrosion is not just about cosmetics and rusting, however, but can also affect edge performance. This steel, as the name implies has a professional styling to it. For decades, different steels have been made to fit this category. 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. The bump in hardness comes from precipitation of fine carbides in the steel, which include chromium carbides. This is also a powder-metal steel produced by American steel company Crucible. 14C28N steel also has excellent wear resistance due to its high chromium content. W-2 Knife Steel Benefiting from 0.2 percent vanadium content, W-2 holds an edge well and is reasonably tough. Many knife enthusiasts are concerned with categorizing steels as excellent, good, poor, etc. 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. The steel is susceptible to overheating during hardening do not overheat. The benefit of this, of course, is that the steel holds an edge for a very, very long time. Not as tough as the best carbon steels, it's tougher than most . I used to work for a company that did reclaimed old growth lumber (swamp cedar, old growth pine and oak beams, etc) and we went through planer blades twice as fast as the cabinetry shop next door (turns out the neighbors like it when you put all the loud businesses together and far away), which mostly cut fresh cherry, oak, maple, hickory etc. M390 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. Divers, sailors, and anglers need knives that will resist corrosion above all else. Chris Reeves version, which is about two points less hard than others, is quite good. HAP40 https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/. Is it similar but worse or better at one of the 3 things? Its tough, but thats about it. 1. Continue with Recommended Cookies. the problem is in the innumerable combinations of grades, grains sizes and coatings available. It improves wear resistance and hardenability. AR-RPM9 I did a test with knives in 440A (stainless), D2 (high alloy steel with some corrosion resistance), and 1095 (no corrosion resistance). 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). S35VN most knives are being made out of these and other mediocre steels like 14c28n, 420j2, 425m. D2 will go through a lot more rope at 58-59 hard than AEB-L will at 64 hard. Only a few years ago Elmax was pricey, but competition has driven it down to reasonable levels, making it a decent value. CN Vs VG-10 The Japanese steel, VG10 offers slightly higher edge retention but has the same level of hardness as 14C28N. 14C28N is the highest-selling steel of Sandvik, a Swedish steel company. Anybody know how the Sandvik stacks up against all these other steels. Steels 7Cr and below arent worth your time or money. 12C27 Around 61 Rc usually. These steels are best for knives that dont see impacts and are some of the most difficult to sharpen. However, many kinds of wood are REALLY tough and very hard on blades. ZDP-189 can tarnish, though not as easily as 3V. There was significant sharpness loss with 1095, almost none with 440A, and D2 was in between. Not every wood is soft pine. On the other hand, Speed safe assisted opening allows for easy blade deployment with the use of a simple pull back on the ambidextrous flipper. Thanks Larrin, All Rights Reserved. Things are similar with resistance to chipping and edge deformation. Corrosion on knife steels most usually takes the form of rust, patina, and staining. 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. 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. But among the steels youll find at Cabelas and the like, this is a pretty good choice. Which one is right for you? what does a cvn of 40 v.s 20 mean? Even premium steels can have poor performance with poor heat treatment. The following are less common steels, but theyre definitely worth tracking down. Corrosion is not only cosmetic. I havent tested Sleipner yet. BD1 is excellent budget steel, very similar in composition and performance to GIN-1, a Japanese steel used a decade ago by Spyderco. Distilled water can separate steels that are stainless vs those that are not. Save my name, email, and website in this browser for the next time I comment. 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. Crucible intends SPY27 to be good all-around knife steel. Having 1.5% Carbon does that. 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. Read more. The old rule in steels used to be corrosion resistance, toughness, or hardness choose two. But SM100 (the trade name for Nitinol 60) threw that out the window when introduced to the cutlery world. 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. See the chart below showing 52100 steel that was overaustenitized (unintentionally) by a knifemaker that sent me specimens for toughness testing. 14C28N. If you are looking for a high-end knife on a budget, the varieties of both steel will serve you. Socould you please clarify which steel is the outlier and which is the line>. 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. The Vargo Sobata 398 is unlike any other knife on this list. Read more. Only a skilled blacksmith can make Damascus steels, so they tend to be expensive. High Alloy Tool Steels and High Speed Steels. However, high wear resistance means that abrasives are used up more rapidly, more careful grinding is necessary to avoid overheating, finishing and polishing is much more time consuming, etc. However, I would argue that pure material removal is usually not the limiting step for ease in sharpening. But in my experience, it has been nothing but great. VG 10 Steel, https://knifebasics.com/author/freelancer/, How To Choose Between The 14C28N And The D2, 14c28n Steel Is Good for Knife? Although it should be noted that there doesnt seem to be a need for the stainlessness on a wood working tool. Thanks in advance, Simon, For hard use everyday cutting in a packing company, Everything from fome, cardboard, tape, thick plastics, And plastic wrap that is against metal. I especially appreciate the geometry/edge retention/toughness comparison with photos. it seems like all the pieces are in place to develop an algorithm for this. S90V Alloying elements are an important ingredient vital in getting the best steel for the job. These properties make steel a good choice for making kitchen, fishing, and everyday knives. This is an American-made powder steel. Cold Steel still uses VG-1 on some knives, and, for the money, it does well. 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. But yes, I would assume that the general performance would still be relatively similar between them without evidence to the contrary. Between the assisted open, weird looking texture designs, and the stainless steel handle, the Cannonball has a lot of features I don't normally like, but even I have to admit it's a good design for the price. 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. But it would be my recommendation for applications requiring extreme corrosion resistance. Spyderco is the only production company using this steel, though Michael Gavik of Gavko knives produced a number of customs in LC 200N. There has been some internet controversy over the grinding and heat treat of this steel. D2 steel also offers similar toughness levels as the 14c28n steel, so both aren't really prone to chipping with proper use. Its OK to be a steel snob, but keep in mind that you dont have to if you want a good knife. 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. They made planer blades out D2 for its edge retention. Can you contact me via my email address so I can send you a copy in PDF and epub. Properties: 14C28N: D2: Edge retention: 4/10: 7/10: Ease of sharpening: 6/10: 3/10: Corrosion resistance: 4/10: 4/10: Toughness: If youre having trouble finding the steel you want, see if another manufacturer makes something much like it. Sharpening the knives might be challenging, but the D2 knife is high quality and affordable. I have a question about the chart The table shows combinations of knife steel properties for different classes of steel. But unlike most high-end steels, SPY27 is an easily user-serviceable powder steel. Not every element is shown in the charts. 9Cr is the top end of the series and is quite good as good or better than AUS-8. But Ive found it lacking in hardness, even when compared to cheaper steels like AUS-8. In that case the difficulty in sharpening would be the inverse of the edge retention rating. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. There you said 7.6 for 420HC. The studies confirmed that the primary controlling factors are hardness of the steel, volume of carbides, and hardness of the carbides. In a pocket knife the total amount of steel is rather small. The ultra high corrosion resistance steels Vanax or LC200N max out around 60-61 Rc instead. Five years ago, S30V had a premium price. I reserve the right to change my ratings based on new information. The both blade are equally wear resistant. This is a nitrogen steel that is extremely corrosion-resistant so much so that its used in knives designed to go in salt water, among the most difficult conditions knives are used in. Here, read on for an in-depth look at common knife steels as well as the best knife steels around. 1. Let's compare 14c28n steel with other steels, and for this, I use four criteria; Edge Retention, Corrosion resistance, Ease of Sharpness, and Toughness and on a scale of 1-10 (10 being the highest) let's see the performance of each steel. as you mentioned catra indicates the edge angle as being by far the most important variable. Oh, thats great, thanks. BD1 isnt terribly hard but sharpens easily. D2 holds it for longer. I have an article that lists off the major mistakes often made in heat treating. These images are taken from my book Knife Engineering. just recently the idea occured tome to sharpen a planer blade like a knife and check out how it performs. That says to me theres a measurable abrasive quality to wood for sure. Top quality steel yields perfect toughness, edge retention, wear and corrosion resistance, an easy to sharpen, long lasting and durable everyday carry that will fast become a user favorite. Wear resistance comes from hardness and carbides, hard particles formed between carbon and another element like Vanadium or Tungsten. 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). I have a few examples below for steels that I have ranges of hardness tested for both toughness and edge retention. This is a very important factor when selecting a steel for your knife blade, especially if you plan on spending a lot of time outdoors in an area with high humidity.. S30v is a higher ranked steel and considered a true Stainless Steel, with a 14% . Many steels are very similar to one another but go by different names from different manufacturers. It is certainly possible for a knifemaker or heat treating company to do a heat treatment that will have suboptimal properties. Extra kudos for your mathmatical steel composition to edge holding model thats really impressive work. 52100 Instead, Vargo titanium uses a unique material called sintered titanium-ceramic alloy. Thanks again for everything you're doing, it's a tremendous resource. Im going to give the ratings first and then give more explanation about how the ratings were created. 14C28N knives offer excellent corrosion resistance and toughness. However, it falls behind the Bohler steel in corrosion resistance. Cronidur 30 Its hard to imagine a more rust-inducing environment than saltwater and fish guts. there seems to be an optimal procedure for every alloy (provided its heat treated to industial standards). 52100 and CruForgeV are good for general purpose knives. CPM 3V This is a bit of a guess because I cant find un-notched Charpy data on it. you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. Thanks! 14C28N is a stainless steel that was developed specifically for use in knives. This is a midprice steel with matching performance. There are a lot of different types of steel out there . 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. Is there a reason SG2/R2 are not included in the lineup, despite being one of the most popular ones? The most balanced is CPM-MagnaCut which is in an area all by itself on the chart. Its high hardness and relatively high toughness also make it an excellent choice in cutlery. Toughness and edge retention are generally opposing properties and it is difficult to improve both of them at the same time. The material increase machinability and strength. I know it's much more stainless and corrosion resisitance, but what about wear resistance? However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. Uddeholm lists it as somewhat worse in toughness than A2 but somewhat better in wear resistance. One argument I see consistently leveled against 8Cr13MoV compared to AUS-8 is that of the consistency of the composition. It is among the best steel that will offer exceptional toughness while still maintaining excellent corrosion resistance. Aluminum oxide is used in most common sharpening stones and it is softer than vanadium carbide, which makes sharpening high vanadium steels more difficult. This is good for ease in heat treating in large batches and for even cooling that greatly reduces warping and size changes. Let the job at hand be your guide. The critical difference between these two sheets of steel is their corrosion resistance. 14C28N is essentially AEB-L (or perhaps more accurately Sandvik 13C26), but with improved corrosion resistance. If you want a sharp knife for outdoor or indoor use, D2 knives will not disappoint you. and why would anyone want to use it when 420HC looks so much better for a simple stainless steel option. There is buzz out there but I havent seen anything solid yet in the world of steel. Combination of knife steel properties. ), intended use will give you all the answers. 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. Or is this an argument that tends to be rooted more in the presumption that Japanese steel > Chinese steel than any practical difference in reality? Anthony Sculimbrene authors the blog EverydayCommentary.com. Get for a complete guide about other steel; you can read 14c28n vs 8cr13mov reviews. Here is the article by Larrin on 48 steels. These steels are the good old hard-working steels. High toughness steels can be produced without powder metallurgy and also have low wear resistance for lower manufacturing costs. 14C28N steel is known to offer among the best if not the best toughness in knife steels out there. I have not provided a rating for ease in sharpening. Should you continue to scroll further, you may find yourself lost in a seemingly endless list of knife steel wealth and knowledge. I forgot, I got the higher carbon steels will have higher edge retention from this website. How long sharpen? in the correct place for the stainless-toughness-edge-retention graphic? It wont hang long with high-end powder metal steels(a method of making steel using ultra-pure micrograins of steel that are heated and pressed together). 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. The knife does dull faster. Low Carbon steels like AEB-L wont hold up to wood cutting even though it can hit 64 hard, it just doesnt have enough Carbon. This means consumers should be able to maintain these quality knives at home. It has enough water-fighting properties that it can be used in marine environments. Toughness is a measure of how much resistance a steel has to fracturing. Is Vancron SuperClean a good choice for a chef knife? But in use, Ive found nothing that withstands the abuse that 3V can take. With a high level ofedge retention, corrosion resistance, and toughness, it does most everything quite well. I am just grasping at straws here, but from the data you shared, it seems like toughness does increase faster than edge retention decreases: it is harder to get a very high edge retention knife that will still be somewhat tough compared to a very tough knife that will still hold an edge ok. 440A Ive found S35VN less chippy even at the same hardness. Notify me of follow-up comments by email. 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? When the blade gets messed up I just replace it. XHP is an exceptionally well-balanced steel with excellent all-around attributes. Thats a little too far, but you get the point.). Heres a brief description of their impact on the resulting steels properties. The ratings I have are for an optimal heat treatment. Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. In all of the cases above, properties are greatly controlled by carbides. It applies to both of course, hence why there isnt a separate label. 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. 14c28n has less carbon and chromium as compared to 9Cr steel. The biggest factor for cost of knife steel is whether it is produced with conventional ingot technology or powder metallurgy. Below shows charts summarizing tests of different steels for the major categories discussed so far, low alloy steels, high alloy non-stainless steels, and stainless steels. You cannot leave your 14C28N knives in water overnight and expect them not to rust. 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. More expensive powder metallurgy steels in this category include M390, CPM-S35VN, Elmax, CTS-XHP, CPM-S30V, and CPM-154. D2 at 58 hard will cut much more rope than AEB-L at 62. Looks like there is no reason to us it over 420HC. Rust Test includes:D2 from Bestech and WE1095 from shop8Cr13Mov from Spyderco420HC from BuckWalmart knifeY Start (Marked D2)Follow me at:Twitter: https://twi.
