Description

One bar of Crucible CPM 20CV Stainless Tool Steel measuring 3.5 x 38 x 914 mm. A high alloy premium martensitic stainless tool steel.

CPM 20CV steel offers exceptional wear resistance for incredible edge retention due to its elevated level of vanadium carbides. It also has an excellent corrosion resistance as a result of its very high chromium content. CPM 20CV has a great balance of corrosion resistance, hardness and toughness. Strongly regarded for small to medium knives including utility and folding knives.

Produced by the Crucible Particle Metallurgy process, resulting in a finer, more uniform carbide distribution that lends improved toughness and grindability to highly alloyed steels.

CPM 20CV is often considered Crucible’s version of Böhler’s M390.

Comes annealed (soft) and Blanchard surface ground to remove mill scale.

Alloy Composition:

Although it is hard to work with in a hardened and tempered state, it does keep superior edge retention.CPM M4 is a high vanadium special purpose high speed steel exhibiting better wear resistance and toughness than M2 or M3 in cold work punches, die inserts and cutting applications, for this reason it is widely used in competition cutting.
