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.Tristelle alloy TS-2 is an alloy of 35Cr-10Ni-12Co developed to withstand both corrosion and galling. This alloy relies on the formation of chromium-rich carbides during solidification. It is the intermediate carbon content alloy in this family, (See Alloy Digest SS-662 and SS-672) and is recommended for valve service.
