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.Crucible A-286 is an age-hardenable austenitic Fe-Ni-Cr alloy designed for service up to 704 deg C (1300 deg F) on jobs requiring high strength and good corrosion resistance at the operating temperature. The alloy offers high ductility in notched sections. Crucible A-286 is used in jet engines and superchargers for various high-temperature components and is one of the few age-hardenable alloys used for bolting in the ASME Boiler & Pressure Vessel Code.
