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.Allegheny Ludlum AL600 alloy is a nickel-chromium alloy designed for use from cryogenic up to 2000 F(1093 C) temperatures. Its nickel content provides resistance to reducing environments and stress-corrosion cracking. Its chromium affords resistance to mildly oxidizing conditions. It has excellent resistance to oxidation to about 2000 F(1093 C).
