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.RA85H is a fully austenitic heat-resistant alloy modified with silicon for resistance to carburization. An addition of aluminum confers good oxidation resistance and improves resistance to sulfidation. The fine grain size of this alloy in the solution annealed condition provides unusual resistance to thermal fatigue in applications where it is subjected to quenching.
