Crucible 154 CM is a modification of 440C martensitic stainless steel to which molybdenum has been added. Crucible 154 CM has better corrosion resistance, better wear resistance, and better hot-hardness than 440C. For knifemakers, it offers better edge retention than 440C. It also has higher attainable hardness and better through hardening characteristics than 440C. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on corrosion resistance and wear resistance as well as heat treating and machining. Filing Code: TS-831. Producer or source: Crucible Industries LLC.
