Crucible CPM 420V is a unique tool steel made by the Crucible particle metallurgy (CPM) process. The alloy is designed from a martensitic stainless steel based analysis with added carbon and vanadium for exceptionally good wear resistance. CPM 420V offers significant improvements over CPM 440V in both wear and corrosion resistance. The exceptional wear resistance and good corrosion resistance of CPM 420V make it an excellent candidate to replace 440C and other corrosion- and wear-resistant materials, particularly where increased wear resistance is a primary concern. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on corrosion and wear resistance as well as heat treating and machining. Filing Code: SS-736. Producer or source: Crucible Service Centers.
