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.Pyromet 600 is a corrosion-resisting nickel-base alloy, having a very desirable combination of high strength and workability, both hot and cold. It has high strength and resistance to oxidation at high temperatures. It is designed to meet the highest quality of the nuclear industry.
