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.Pyromet 882 is an air-hardening 5% chromium tool steel recommended for high temperature applications up to 1000 F. It has extremely high tensile and creep strength. It is used for such critical applications as structural components in aircraft and missiles which require either extremely high strength (over 260,000 psi) at ambient temperature or high creep and rupture strength at temperatures of about 800 to 1200 F.
