CPM technology helps to make homogeneous steel by distributing carbides in the blade evenly. It is also easier to machine and polish than CPM S30V. The main changes we expect from S45VN vs S35VN and S30V are an improvement in corrosion resistance due to the increase in Cr of about 1%. Bark River Knives Canadian Special 3V LT Black Canvas Micarta Red Liners. CPM 3V steel has the following steel composition (Note the high amount of vanadium content which produces some of the smallest and hardness carbides in knife steel. By using a much finer grain structure and adding small quantities of niobium (hence the “N”) they were able to make the outstanding S30V easier … They also have a range of other standard knife steel grades like ATS-34, 440C, 154CM, … In 2009, Crucible Steel introduced an update to CPM-S30V to meet the needs of renowned knife maker Chris Reeve that they called CPM-S35VN. I have personally had problems with staining on my A2. When looking at quality American-made knives, you'll notice that S35VN and S30V steel are two of the more popular steels for knife blades. This is the principle reason to select CPM 3V for a knife.Edge Retention/Wear Resistance - CPM 3V steel does not hold its edge as well as some other steels like S35VN or S30V. CPM Cruwear has held an edge better than S35Vn for me. Conclusion A2 vs 3V By DLT Pro Staff Writer Matt Westendorf When it comes to steel choices we are fortunate to have a lot of options be it stainless, good old tool steels or the new breed of super steels. Many of the other previous Crucible Particle Metal (CPM) steels were developed for the plastics manufacturing industry and other advanced manufacturing industries. Its chemistry has been rebalanced so that it forms some niobium carbides along with vanadium and chromium carbides. It is a step forward from S35VN but its improvements are incremental better not orders of magnitude better. Because of these manufacturing features, knifemakers might choose to use S35VN rather than S30V from a process perspective and/or for an extreme-use fixed blade for slightly increased toughness. It is also easier to machine and polish than CPM S30V. Their carbides provide extreme hardness in the steel alloy matrix. Bark River Knives Tundra 3V Red Elder Burl #2. It will likely oxidize over time depending on the working environment, 3V steel is not stainless. Conclusion. Comparing my Bark River Bravo 1 LT in 3V to a 1095 blade, the difference, over a large sample size, is clear even to someone like me (a relative fixed blade newb). The addition of niobium reflects the addition of N in the name of the steel. Price $224.96. Who uses it: Bark River Knives, Fiddleback Forge , Koster Knives. In the manufacturer CATRA dataset, CPM Cru-Wear was in between 3V and Vanadis 4E, as would be expected by its carbide content. CPM S45VN is a martensitic stainless steel designed to offer improved corrosion and wear resistance over CPM S35VN. This high-end steel foundry process leads to superior stability, toughness and grind-ability with a cleaner finish than traditionally made steel. By hard use scenario I mean some type of last ditch, save your life type scenario where it needs to chop wood, possibly defend against a wild animal, almost certainly entirely fictional scenario. 3V and CPM Cru-Wear have decent edge retention, with CPM Cru-Wear being a bit better. Its chemistry has been rebalanced so that it forms some niobium carbides along with vanadium and chromium carbides. It is designed to provide maximum resistance to breakage and chipping in a high wear-resistance steel. Bark River Knives Tundra 3V Green Canvas Micarta. 0.3.1 S35VN鋼モデルはこちら！ 0.4 Elmax鋼 0.4.1 Elmax鋼モデルはこちら！ 0.5 CPM Cru-Wear . What is remarkable about the steels is that both were developed for the knife industry! Substituting niobium carbides for some of the vanadium carbides makes CPM S35VN about 15-20% tougher than CPM S30V without … A Japanese powder steel, ZDP-189 is essentially the polar opposite of 3V — it’s uber-hard instead of uber-tough. Also, I haven't used S35Vn from Spyderco because I have so much of it from other companies (obviously heat treat quality varies). CPM 4V. They also offer Crucible steels like CPM-154, 154CM, S30V, S35VN, CPM-3V, and CPM-M4.
