Material Notes:
Crucible 154 CM is a modification of 440C martensitic stainless steel to which molybdenum has been added. 154 CM has better corrosion resistance, better wear resistance and better hot-hardness than 440C. For knife makers, it offers better edge retention than 440C. It also has higher attainable hardness and better through hardening characteristics than 440C.Information provided by Crucible Specialty Metals.
