The impact toughness is enhanced by the fine grain size, small carbides, and superior cleanliness of the powder metallurgy (PM) microstructure. It's still one of the best, but a lot of folks seem to think it's been left behind a bit by better steels that are easier to sharpen and less prone to chipping. Toughness (how durable the blade is) CPM M-4; Quick View. Regular prices for Express Shipping and Oversize Shipping still apply. The addition of molybdenum also helps to keep away corrosion, specifically the type that causes pitting in the steel. CPM ® 3V: CPM 3V is a high toughness, wear-resistant tool steel made by the Crucible Particle Metallurgy process. 0.1 A2鋼 . S30V is generally regarded as one of the best-value fine knife steels in the industry. CPM is a trademarked name for a process that is also called Powdered Metallurgy or PM steel. Particle metal steel manufacturing is only done by a handful of steel manufacturers around the world. Cold Steel - XHP vs S35VN - Edge Retention Comparison, also unleashed - Duration: 9:52. Bark River Knife & Tool over the past few years has started making more and more of their models available in a variety of steels including A2 (the old standby), CPM 3V and many more. Who uses it: Bark River Knives, Fiddleback Forge , Koster Knives. Heat treatment (The hardness of the steel) The S35VN or CPM S35V is a high-end martensitic stainless steel made by @Crucible, high in Carbon, Vanadium, and chromium designed to offer a great balance between toughness, hardness and corrosion resistance.It’s used in long-wearing Specialty cutlery, Plastic Injection and Extrusion Feed Screws and Dies, Wear Components for Food and Chemical Processing, and of course in the Knife Industry.

Be first to receive news about sales, coupons & new promotions. Many people have asked me how A2 compares to CPM-3V in corrosion resistance. S35VN Steel All prices are in Canadian dollars. 52 54 56 58 60 62 64 66 As Q. According to Crucible, 3V steel is meant to be heat treated in 58-60 RC (Rockwell Hardness Measurement) range for knife blades. Quick View. This means that the combination of alloys in the steel make it more susceptible to dulling with repeated use. CPM 3V .156 (5/32”) Previous: N/A Current: NP69010 ; CPM 3V .187 (3/16”) Previous: N/A Current: NP69719 ; CPM 3V .250 (1/4”) Previous: NP68297 Current: NP69719 . S30V and S35VN are each classified as a premium steel, as they offer an excellent combination of quality and affordability. There are many different types of steel that your knife could be made from. Again, consider the four properties of knife steel:Toughness - This steel has outstanding toughness, so you can expect it to survive abuse in the field and in survival scenarios. The difference between the two is in the details. Barkriver Aurora 2 CPM 3V. CPM 154 S35VN; EDGE RETENTION: 4/10: 6/10: EASE OF SHARPNESS: 5/10: 6/10: CORROSION RESISTANCE: 6/10: 7/10: TOUGHNESS: 5/10: 6/10: S35VN offers better edge retention, better toughness and better corrosion resistance compared to the 154CM Steel. CPM Cruwear has held an edge better than S35Vn for me. Price $224.96. Depending on the heat-treatment of the knife, you can expect knives made with one of these steels to have a Rockwell Hardness between 58 and 61. Its chemistry has been rebalanced so that it forms some niobium carbides along with vanadium and chromium carbides. S35VN is a fantastic and well-balanced steel that is very corrosion resistant, while still holding and edge for a long time, and is fairly easy for makers to work with as well. 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 … 400°F 600°F 1000°F 2000°F (1095°C) 1950°F (1065C) 1900°F (1040°C) DS413 6/10 CPM S35VN ©Crucible Industries LLC Printed in U.S.A. Barkriver Gunny CPM S45VN . I can go 3v or s35vn. Be first to receive news about sales, coupons & new promotions. It is a step forward from S35VN but its improvements are incremental better not orders of magnitude better. EDGE RETENTION: 7 CORROSION RESISTANCE: 7 EASE OF SHARPENING: 5. This composition makes it tougher (resistance to edge chipping) without reducing the wear resistance (edge holding) of the steel. Yet it is easier to machine, grind and polish due to the substitution of niobium for a part of vanadium plus the addition of molybdenum. In 2009, Crucible and Chris Reeve introduced an ever so slightly superior version of their excellent S30V steel and named it S35VN. CPM-S35VN. CPM technology helps to make homogeneous steel by distributing carbides in the blade evenly. This makes each type a great steel for everyday use, especially in tough environments. The specific formula for S35VN knife steel - aka the "ultimate mainstream steel" - is 3% vanadium, 1.4% carbon, 0.5% niobium, 2% molybdenum, and 10.5% chromium. Die Buchstaben “S”, “V” und “N” beziehen sich auf die Begriffe “rostfrei”, “Vanadium” und “Niob”. The handle is great for most hand sizes and types and the control and comfort it gives is outstanding. CPM American Steels Both S35VN and S30V steels were developed in a collaboration between Chris Reeve and Crucible Industries, a New York-based steel manufacturer, using Crucible Particle Metal (CPM) technology. Carbides are the hard particles in steel that allow the blade to keep an edge. It makes a great field knife blade that is tough and unlikely to break with heavy, near abusive, use. It offers impact resistance greater than A2, D2, Cru-Wear, or CPM M4, approaching the levels provided by S7 and other shock resistant grades. Also, I haven't used S35Vn from Spyderco because I have so much of it from other companies (obviously heat treat quality varies). 3V and CPM Cru-Wear have decent edge retention, with CPM Cru-Wear being a bit better. 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. This steel continues to be one of the best knife steels on the market for a wide range of knife uses and applications. In the manufacturer CATRA dataset, CPM Cru-Wear was in between 3V and Vanadis 4E, as would be expected by its carbide content. Disadvantages: Relatively more difficult to sharpen than predecessor steels like A2. CPM 440C CPM D2 154 CM CPM CPM CPM CPM S35VN 3V S30V M4 S90V 10V . Bark River Knives Canadian Special 3V LT Black Canvas Micarta Red Liners. S35VN Stahl besteht aus 1,4 Prozent Kohlenstoff, 14 Prozent Chrom, … Substituting niobium carbides for some of the vanadium carbides makes CPM S35VN about 15-20% tougher than CPM S30V without … Bark River Knives Tundra 3V Green Canvas Micarta. Prices do not include applicable taxes. When comparing CPM 3V steel vs. A2 steel, 3V is superior in edge retention and toughness with a big win for CPM 3V.Heat Treatment - Heat treatment effects the edge retention and toughness and is determined by the knifemaker. CPM S35VN is made with 14% chromium to maximize stain resistance and corrosion without giving up too much toughness. What it is: CPM 3V is a "Crucible Particle Metallurgy" carbon tool steel, widely regarded as a "super steel" for its properties and performance. 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). Weight: N/A: Dimensions: N/A: Reviews There are no reviews yet. Less hardness in the heat treatment will mean more toughness but less edge retention; like many properties with knife steel it is a trade-off in qualities.Corrosion Resistance - CPM 3V steel is not stainless steel, it will oxidize if not properly cared for. Quick View. ... CPM 154 Vs O1 Edge Retention Test - Duration: 13:11. Applying a very hard, scratch resistant coating such as PVD or DLC to a blade surface will help slow corrosion where the coating covers the blade - which general excludes the cutting edge.I hope this article has been informative about the CPM 3V Steel, one of the toughest blade steels available for use on knives. 13:11 .
