Different companies can vary some between each other making the same product, while a single company is going to be more consistent. A hunting knife has a singlepurpose: processing meat after akill. My favorites of the high edge retention group are Vanadis 8 and CPM-10V. The hardenable grade of titanium (Beta C Titanium) reaches up to 45 or so rc. 2. 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. CTS-204P and CPM-20CV are nearly identical steels made by other manufacturers. Even it enhances corrosion resistance and wear resistance. 14C28N is the highest-selling steel of Sandvik, a Swedish steel company. What is pulling that line high and to the right? D2 steel is a ordinary tool steel and knife steel. Theres still a lot of misinformation being pushed by influencers especially in knife steel rankings. . Finally, in this 14c28n vs d2, we hope you get the right one. By that I dont mean that a better heat treatment is not possible, but that major mistakes in heat treating are avoided. Id like to quote some of your toughness, edge retention and corrosion resistance for balanced midfield steels, including yours, in some data tables. Knife Steel Rust Testing 1095, 8Cr13Mov, D2, 420HC, Walmart - YouTube Crucible intends SPY27 to be good all-around knife steel. The unique process used to make LC 200N results in a fine-grain structure. 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.). S110V has improved corrosion resistance at the cost of some toughness compared to S90V. There are still a few things I dont know but we have enough information to make educated guesses where data isnt available. D2 steel also resists chipping better than most stainless steel types. Now that is power planer blades, but the principle stands, less carbon and alloy isnt the best for wood working and Id use a steel like 26C3 (1.25% C .30%Cr) for my hand tools and temper them to around 62 hard and use the best angle for wood shaving, not the best angle for cutting rope. Did you change the estimate based on more testing? : 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. Thanks to powder metallurgy, youll find even better edge retention on the high end. It would be interesting to try to develop a conversation between /geometry/edge retention/toughness, so we could say e.g. Im a woodworker and Im interested in making better performing plane irons and chisels. That says to me theres a measurable abrasive quality to wood for sure. 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.

However, D2 steel has better edge retention, while 14C28N offers a better sharpening experience. Monday-Friday The biggest factor for cost of knife steel is whether it is produced with conventional ingot technology or powder metallurgy. This can turn the ultra corrosion resistant LC200N or Vanax into a normal stainless steel that will rust with only 1% saltwater. A European powder-metal steel used in higher-end knives, Elmax has an advanced formula, and the result is a very good all-around steel, a generation ahead of formulations like 154CM. Most steels use carbon to increase hardness, but 14C28N uses nitrogen, boosting hardness without the normal penalty of increased corrosion. I cant seem to match steel to the SS data points on the toughness/tcc graph. The edge retention and ease of sharpening have been what we expect with D2. Around 61 Rc usually. Sandvik 12c27 Stainless Steel Review: Is it Really Great But to learn more about these and other attributes, read our related outdoor knife buyers guide. Coarse-carbide tool steel grades. Low Alloy tool steels have small alloy additions to increase hardenability so they harden more easily in oil rather than water. While not a powder steel, 154CM is widely used in nicer knives. 420HC, 420, and 5160 all offer off-the-charts toughness. [Steel Knife Review], What is 14c28n steel? quite possibly the best steel youll find on a sub-$30 production knife. If I made some plane irons from AEB-L at 63 Rc (where its still tougher than 1095 at 59-60 Rc, the standard vintage steel in plane irons), could I drop my sharpening angle from 30-35 to 25? What it is: D2 is a carbon tool steel with a relatively high chromium content, prompting some to call it a "semi-stainless" steel. You can see micrographs of different knife steels to compare their carbides in this article. I do not have rust issues with it (as long as I have a good finish) some heavy stonewashed finishes rust easier. You can read an article I wrote on budget steels here. 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. Many steel ratings articles pay lip service to the importance of heat treatment without providing examples. This grade can be treated cryogenically to improve edge retention. Since the heat treatment is done before you get your knife, and its impossible to tell how good the heat treatment is with your eye, you often must rely on the manufacturers reputation for a good heat treat. The Vargo Sobata 398 is unlike any other knife on this list. In many cases the cost of working with the steel for the knife companies is more significant than the cost of the steel itself. For example, Bohler M390, CTS-204P, and CPM-20CV are all nearly identical and indistinguishable in practice. : at a given toughness, magncut will have better edge retention in real life applications than s90v if it has optimal geometry (or maybe it wouldnt, just an example). The Best D2 Steel Knives And What Makes Them Great Knifemakers use dozens of steel types to create knife blades. 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. Been here before? Ease of Sharpening: One advantage of 8Cr13MoV is that it is easier to sharpen than D2 steel. Why do knives make the best gifts? 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. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% its relatively corrosion-resistant. Thanks. LC200N has similar properties to those two but with saltwater levels of corrosion resistance. But a few overly vocal forgers were making claims about it that clearly were not true especially when comparing it to 5160. 14C28N VS Steel. its like with cars, most of them are not a corvette or a porsche. Its hard to imagine a more rust-inducing environment than saltwater and fish guts. Any idea where it would be on the hardness and toughness scales? I was thinking maybe Sleipner or A2 would be best if a PM steel was out. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. Generally seen as a slight upgrade to the 440C/VG-10/ATS-34 caliber of steel, its a decent all-around steel with good corrosion resistance, decent toughness, and only modest hardness. The big names in powder metallurgy are Crucible (CPM- steels), Carpenter (CTS- steels), Bohler Microclean (M390), and Uddeholm Superclean (Elmax, Vanax). Another important caveat before we get to the ratings are that these are for the steel only. 1095. This is the basis on which I do the ratings rather than a linear scale. CPM 4V As wear resistance is increased the differences between conventional and powder metallurgy steels become greater. There are also hardness/toughness and hardness/TCC charts.but no tables backing this charts. 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. I have not provided a rating for ease in sharpening. However,M390, CTS-204P, and CPM-20CV are all pretty difficult to resharpen, so maintain that edge! . 2. at least it has some vanadium over the 420hc. Deburring of edges often takes even longer than removing material to produce the edge. That mixture has one goal in mind: making a great steel for people worried about rust and corrosion. This is especially important for chopping knives and for knives with thin edges for enhanced cutting ability and edge retention. Are you familiar with anything similar on the metallurgy/knife steel side of things? 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). AR-RPM9 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. Everyone has their own opinion on what they deem the best folding EDC knife. This was described in this article on Vanax heat treating. 14c28n vs d2 : r/chineseknives - reddit 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. 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. 9cr18mov vs 14c28n. H2 Different heat treats have emerged over the years, but one has risen to the top as the best:Bob Doziers D2. The following are less common steels, but theyre definitely worth tracking down. Most of the user loves this one that has received a lot of attention on this site. When it debuted, Sal Glesser described XHP as a combination of D2s hardness and 440Cs corrosion resistance. Read more. Its possible that there are steel manufacturers with better processing which would lead to an even carbide distribution but I cant say that without seeing it for myself. 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. 14c28n has less carbon and chromium as compared to 9Cr steel. The high hardness makes it all but impossible to sharpen and machine. I tested its edge wear resistance but not its toughness yet. In other words, heat treating a steel to its maximum hardness does not necessarily mean reduced corrosion resistance. D2 is not a bad steel, but it has been around a long time and is somewhat mundane by current standards. Vanadium carbides are among the hardest that form in steel, and chromium carbides are in between iron carbide and vanadium carbide. Is this at the same hardness? The majority of knives target 63 Rc or below so this limitation of stainless steels does not always come into play but can be an important factor for certain knives targeting high performance and thin edges. Some steels are more difficult to manufacture for the steel company or have more expensive alloying elements so the cost is increased. Thank you for putting this together, incredibly useful! AEB-L and 14C28N also have moderate edge retention though of course much lower than vanadium-alloyed powder metallurgy steels like S30V or M390. I feel like it sharpens as easy as D2. Despite its wonderful performance, XHP is actually not terribly expensive compared to other high-end, all-around performers. Softer steel usually forms larger burrs and they are more difficult to deburr. This is one of the better steels on the market. This is a virtually stain-proof steel suitable for all sorts of aquatic environments. im led to believe tha the melting procedure is more important with these steels than the exact composition. 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. 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. Take a look at this edge retention test. This is a non-powder Japanese steel used primarily in Spyderco knives. And Mn and Si isnt shown at all for the high alloy steels, even though those elements are added to all of them. Rowens heat treat on ESEE knives that use 1095 is exceptional; KA-BARs is less so. Ive found that most makers harden S30V too much, making it prone to chipping at the edge. They represent the absolute best performers on the market in terms of their specific attributes. Though technically not a stainless steel due to its composition, in use it performs exactly like one. Many knife enthusiasts are concerned with categorizing steels as excellent, good, poor, etc. And given the recipe, it has a low number of carbides, the extra-hard microcrystals in steel that provide the hardness necessary for a stable and sharp edge. He is the mind and writer behind Knife Steel Nerds, the go-to source for all knowledge about knife steel. They have many similarities, including their high hardness, strength, and wear resistance. 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. 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. D2 is a high carbon, high chromium die steel and is the highest carbon alloy tool and die steel typically used in knife making. I am particularly interested in researching knife steel, knife properties, and brands. Must-Have Bowie Knives for Your Collection, What is Micarta and What Makes It a Great Knife Handle, Top 8 Reasons Why Knives Make the Best Gifts, Pocket Clips: Carry Safely and Comfortably, Make a Knife Your Own with Accessories & Customization. -> Maybe prequenched 14c28n could be a little tougher than AEB-L? A good quality knife must have sharpness, great edge retention, and a sturdy handle.
