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.

RA 800H is an austenitic iron-base, heat-resistant alloy with excellent high-temperature strength and good resistance to oxidation in air up to 2000 F (1090 C). High creep-rupture properties are obtained by a solution-anneal treatment followed by a rapid cool; grain size is controlled in the range 1 to 5 on the ASTM scale. RA 800H is free from embrittlement by sigma-phase formation. This alloy is well suited for high-temperature processing in refining or petrochemical service.
