14c28n steel vs d2

This is an American-made powder steel. imo o lot depends on how the blade is sharpened. Its tough, but thats about it. n690 But keep in mind that no steel is perfect for everything. The consent submitted will only be used for data processing originating from this website. Many steel ratings articles pay lip service to the importance of heat treatment without providing examples. 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. We and our partners use cookies to Store and/or access information on a device. 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. You showed some pictures in this article of the effect on what we might call "effective toughness" of thinner edge angles vs thicker edges in the same steel at the same hardness. There one of the best reason that he is highly regarded as a knife designer. 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. As of November 2020, this is Spyderco-exclusive steel. It has high levels of chromium and carbon, making it extremely resistant to corrosion. These steels are typically used by forging bladesmiths, traditional folders, and some production fixed blades. However, even in this case there is the complicating factor of carbide and abrasive hardness. There are so many interactions between them that predictions are difficult without modeling software. A few steels have been added since such as MagnaCut and M398. Knifemakers use dozens of steel types to create knife blades. 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. Ease of Sharpening: One advantage of 8Cr13MoV is that it is easier to sharpen than D2 steel. Steels with very high vanadium content like Vanadis 8, CPM-10V, K390, CPM-15V, etc. I think they are complementary and you should watch/read both. Read more about how it works here. The unique process used to make LC 200N results in a fine-grain structure. In the context of a knife this would be chipped edges or broken knives. One such person is Dr. Larrin Thomas, a professional metallurgist raised by a knife maker and a giant knife nerd. If you want to learn more about a specific steel, you can click it in the sorted listings below. 14C28N and D2 steel are not the same. The performance of these blades are equally admirable. Another important caveat before we get to the ratings are that these are for the steel only. After the steel is quenched it is reheated to a lower temperature to increase toughness and decrease hardness. Very obtuse edges resist chipping better but dont hold their edge as long and dont cut as well. They represent the absolute best performers on the market in terms of their specific attributes. Some steels are more difficult to manufacture for the steel company or have more expensive alloying elements so the cost is increased. Flashlights run the gamut of price and quality. Steel with high wear resistance is more costly to manufacture, as the knife company goes through more abrasives to grind the knives. BD1 is excellent budget steel, very similar in composition and performance to GIN-1, a Japanese steel used a decade ago by Spyderco. 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. Read our full Sobata 398 review here. 14c28n steel has a high Chromium and Carbon percentage. Often used for combat knives. You cant look at only the chromium content of the steel to know the level of corrosion resistance. There was significant sharpness loss with 1095, almost none with 440A, and D2 was in between. Some steels are cooked up specifically with this in mind and are very difficult to make rust. LC200N is produced with a special technique to add high nitrogen, giving steel excellent corrosion resistance on the top! 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. 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. I have a few examples below for steels that I have ranges of hardness tested for both toughness and edge retention. Things are similar with resistance to chipping and edge deformation. Therefore, you cannot purchase the knife for use in corrosive environments. This makes it a great choice if you don't have . This is good for ease in heat treating in large batches and for even cooling that greatly reduces warping and size changes. 52100 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. Most of these steels rely on particle metallurgy and are therefore more expensive. 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. And while it can be hard depending on the heat treat, I have found it easily chips, causing microscopic dings in the edge when hardened to a high level on a thin blade. D2 is another medium-range tool steel. 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. 14C28N steel is the improved version of 13C26 with better rust resistance. Let the job at hand be your guide. Thank you for putting this together, incredibly useful! The steel is an air-hardness tool steel that is considered semi-stainless because of its high chromium content. i understand the samples were treated in the same way. Combination of knife steel properties. More expensive powder metallurgy steels in this category include M390, CPM-S35VN, Elmax, CTS-XHP, CPM-S30V, and CPM-154. Is 14c28n Steel Good For Knives? A Complete Guide - Knife Pulse Its very corrosion-resistant and quite tough. 440B Perhaps a bigger issue with the upper temper is for stainless steels, as there is a significant reduction in corrosion resistance by tempering at 1000F instead of 400F. This steel is quite corrosion resistant and sharpens easily. Maxamet and Rex 121 are so extreme in terms of wear resistance and edge retention that I rated them higher than 10 because otherwise it throws off the ratings for everything else. 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? 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. ), intended use will give you all the answers. Give it a couple of weeks, and feedback will start pouring in. FRN My test is for comparing different steels, not necessarily for a go/no go test for saltwater applications. and why would anyone want to use it when 420HC looks so much better for a simple stainless steel option. Have you tested K390 sufficiently to be able to rate it? But SM100 is not widely available, hard to heat treat and grind, and exceptionally expensive. 14c28n vs. D2 Steel D2 is as rigid as 14c28n, thus has almost equal edge retention abilities. I would like to see the rating and performance on test of the Chinese Steels, that some people use to say its cheap garbage, like 3Cr13MoV, 4Cr13, 4Cr13Mo, 4Cr14MoV, 5Cr15MoV, 6Cr13MoV, 7Cr17MoV, 8Cr13MoV, 9Cr13MoVCo, 9Cr18MoV, 9Cr19MoV, and the 14cr14MovNB to see if they are similar, worse or better than the steels that they copyi believe we gonna have some good unexpected results. And Mn and Si isnt shown at all for the high alloy steels, even though those elements are added to all of them. https://i0.wp.com/knifesteelnerds.com/wp-content/uploads/2021/10/stainless-toughness-10-19-21.jpg?w=757&ssl=1 D2 holds it for longer. AR-RPM9 14C28N knives offer better toughness than D2 knives. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. The brand Bark River uses A2 in many models. 14c28n vs. AUS-8 Steel 14C28N steel also has excellent wear resistance due to its high chromium content. 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? This is the steel used in Swiss Army knives and is excellent for beginner sharpeners. Tanto Spyderco has their own salt spray test setup to determine the corrosion resistance and they determined that MagnaCut is sufficiently corrosion resistant for their salt series of knives. Sandvik 14C28N steel is better than D2 steel in corrosion resistance and toughness. These two knives are a little bit more than a pretty face. The high hardness makes it all but impossible to sharpen and machine. . Below, weve listed some of the attributes you might want out of your steel and given some examples in both the more expensive powder metallurgy steels and more affordable conventionally produced steels. Pretty interesting that regrinding a knife you already have can seemingly take its performance to that of significantly better steels. Without any confusion, you can purchase this set that has a slim, versatile, modified drip-point blade with good slicing capabilities. 1% saltwater will separate between other stainless steels. https://cedric-ada-store.creator-spring.com/listing/brickard-heritage-collectionGood gravy its bricky on thingsSubscribe and hit the bell! CPM 10V I've heard d2 is miles better and i dont want to pay 90 for the p135 and get a significantly inferior blade to paying 110 for the D2 Rat. It's like the difference between average 420HC and Buck's 420HC with the Bos heat treatment, only from a better starting point. I am particularly interested in researching knife steel, knife properties, and brands. Here its 8. Also known as Z-Finit, Zapp produces this steel in America. CRKT and Spyderco use BD1. G10 MC66 There has been some internet controversy over the grinding and heat treat of this steel. 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? Many custom makers enjoy AEB-L, as its easy to machine but still has a high hardness, around 62 HRc. 9Cr18MoV steel Review - Everything You need to Know - Materials Today Using controlled furnace heat treating resulted in toughness around 23-28 ft-lbs at 61-62 Rc, while the knifemaker heat treated specimens were 7 ft-lbs or below. Because of its difficulty in sharpening and machining, its very rarely used and comes with a high price premium. Cookie Notice D2 is carbon steel that has high toughness and durability. The bump in hardness comes from precipitation of fine carbides in the steel, which include chromium carbides. Theres still a lot of misinformation being pushed by influencers especially in knife steel rankings. You also reported 8.6 for 440A in that post, compared to 8.5 in this post. It has enough water-fighting properties that it can be used in marine environments.

Spyderco has produced several production knives with Maxamet, and the steel debuted on the ZT0888. The big difference in properties vs the low alloy steels, however, are the harder carbides that are found in these steels. In other words, Rex 121 would be the most difficult to sharpen and 5160 and 8670 would be the easiest. The 10V specimens tempered at 1000F were 4-5 ft-lbs while the specimens tempered at 4-500F were 7-8 ft-lbs. I have a Winkler Knives Recon model in 5160 steel and even though the knife model is ok, the steel is shit. Corrosion is not only cosmetic. If you are a newbie, sharpening D2 knives will be a struggle, but it is doable with practice and the right sharpening tools. No mainstream companies use SM100, and the niche makers that do usually charge more than $1,000 for knives with SM100 blades. The benefit of this, of course, is that the steel holds an edge for a very, very long time. EDGE RETENTION . Even metallurgists can have a difficult time estimating properties just based on the elements. Therefore, ensure to wash and dry your knives after use to keep the rust away. AEB-L is a non-powder steel produced by Swedish steelmaker Uddeholm. 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/. The D2 version is heavier and harder, but doesn't cut as smoothly. The blackwashed D2 steel blade of the Kershaw Cannonball offers pretty good corrosion resistance for D2. 1. can you strike twice as fast with the knife? Generally this is code for difficulty in abrading away steel. 2. just recently the idea occured tome to sharpen a planer blade like a knife and check out how it performs. Is that regression line (or other trend line?) If youre looking for all all-around best knife steel, youd be hard-pressed to find one better than Bohler Uddeholm M390. 14c28n vs d2 - Which Model For Best - Knifeyellowpages 14C28N and D2 steel are not the same. 1. Also Mo additions improve corrosion resistance for a given amount of chromium. So presumably, wear resistance would be in the 3.5-4 range and toughness in the 5.5-6 range. That way you can get into the steel ratings quickly. This is a non-powder Japanese steel used primarily in Spyderco knives. As a result, there are no production knives with REX 121 steel, though Ferrum Forge used the steel early on in its custom knives and a Kickstarter knife from the Creely Brothers. 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). Old time 8670, 5160 (known to ignoramuses as 51shitty) and 52100 are excellent choices and arguably better choices than 80crv2. But weve tested this metal in the form of the Sobata 398 for nearly a year and have been continually impressed. Hit like and all t. I couldnt find much on 5160 steel and from a knife makers point of view if you are saying youre the preferred supplier of special ops than I dont understand this choice in knife steel. This is to keep the focus on the elements that are making the biggest difference. Corrosion is not just about cosmetics and rusting, however, but can also affect edge performance. 14C28N is stainless steel, and its knives offer excellent rust resistance and toughness than D2 steel. These steels are best for knives that dont see impacts and are some of the most difficult to sharpen. LC 200N is an elite performer, with high hardness, high toughness, and off-the-charts corrosion resistance. We all have our preference, but overall, preference leans towards the pocket knife with a clip. It will take you more time and energy to get a sharp edge, but your efforts will pay off because the blades hold the edge longer.

I love reading through all the data youve gathered and making note of all the trends (Im a physical organic chemist). 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. It has an HRc over 70, usually even harder than Maxamet. The 14C28N, on the other hand, is tougher. In its most basic form, steel is just iron and carbon, but people have been studying, experimenting with, and perfecting steel with other elements for specific applications for millennia. If the knife youre looking at has a 154CM blade, youre fine. S45VN This is especially important for chopping knives and for knives with thin edges for enhanced cutting ability and edge retention. Not impractical fantasy knives, but these two knives that have a col look to them. All about 14C28N Steel - HDMD Knives Blog 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). Continue with Recommended Cookies. Therefore I will be showing the ratings of the steels graphically in terms of toughness-edge retention balance, where steels that are high and to the right have the best combination, and you choose the steel based on the level of toughness or edge retention necessary for the knife. This makes for a great slicing knife and a perfect steel, in my opinion, for a regular-use, everyday-carry folder. A2 Knife Steel Air-hardened tool steel. 14C28N vs. D2. REX 121 is a powder steel produced by Crucible. I have a question about the chart Lately Ive been edcing one of those instead of a nice folder. https://knifesteelnerds.com/2020/05/01/testing-the-edge-retention-of-48-knife-steels/, Unfortunately it all comes down to marketing on everybody involved: Industry, knifemakers, users.
