Abstract CRUCIBLE CPM 9V is a tool steel made by the Crucible Particle Metallurgy (CPM) Process. It is a lower carbon and vanadium modification of Crucible CPM 10V with enhanced toughness and heat-check resistance. This provides CPM 9V with an excellent combination of properties for both hot and cold-work applications. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on wear resistance as well as forming, heat treating, and machining. Filing Code: TS-464. Producer or source: Crucible Materials Corporation.
