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.P/M 625 is a nonmagnetic alloy with outstanding strength and toughness from cryogenic temperatures to 2000 F. It has excellent fatigue strength and stress-corrosion-cracking resistance to chloride ions.
