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.ALTEMP 601 is a nickel-chromium solid-solution alloy with excellent high-temperature properties with good resistance to oxidizing, carburizing, and sulfur-containing environments. The properties make it attractive for applications in aerospace and process industries as well as automotive thermal reactor core components.
