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.An alloy of 30Cr-10Ni-12Co developed to withstand both corrosion and galling. This alloy relies on the formation of chromium-rich carbides during solidification. It is the lowest in carbon of the Tristelle Family. The alloy is recommended for valve services.
