View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.14-4CrMo is a martensitic stainless tool steel with better corrosion resistance than Type 440C. Molybdenum increases the corrosion resistance and produces wear-resistant carbides. The alloy is used for its wear resistance and edge retention.
