What does CPM stand for in knife steel?
CPM stands for Crucible Particle Metallurgy and is a method of producing higher alloyed grades of superior quality than could be accomplished through conventional steelmaking. CPM steel is useful for high-alloy tool steel and high speed steel.
What is CPM knife?
In the knife world “CPM” stands for Crucible Particle Metallurgy. This is a proprietary system developed by Crucible Industries to create a uniform steel composition at a molecular level. This allows the grain of the steel to be incredibly fine with even carbide distribution.
What is CPM 10V?
CPM 10V® powder metal tool steel is a versatile air hardening tool and die steel which provides extremely high wear resistance in combination with relatively high impact toughness. A very large volume of hard vanadium carbides provides the high wear resistance.
Is CPM 3V tough?
From this CPM 3v steel review, you have learned that this is one of the toughest steels available. It’s insanely tough and will excellently resist chipping and breakage, making it suitable for large blades, fixed blade knives, and field blades.
What is CPM S35VN steel?
CPM S35VN is a martensitic stainless steel designed to offer improved toughness over CPM S30V. The CPM process produces very homogeneous, high quality steel characterized by superior dimensional stability, grindability, and toughness compared to steels produced by conventional melting practices.
How hard is CPM 10V?
Annealed Hardness: BHN 255/277. Machinability in the annealed condition is similar to D2 or M2. SG type alumina wheels or CBN wheels are recommended for the best grinding performance with the CPM steels. Critical Temperature: 1540F(838C)….

Is CPM 10V Carbide?
microstructure of CPM 10V steel consists of a ferrite-carbide matrix with equally spaced second- ary acicular and globular carbide phase (see Fig. 3), which, compared to steels produced via classical me- tallurgy, is significantly smaller. For this reason meas- ured hardness after heat treatment was 61 +2 …
