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.CPM 1V is a powder metallurgically produced high-vanadium cold-work tool steel. It is an upgrade to H13 with higher hardness and better temper resistance for longer die life. The alloy also has better heat resistance and higher hardness than H19.
