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.UNITEMP 41 is a nickel-base, precipitation-hardenable alloy that retains high strength and finds most use in the temperature range 1200 to 1800 F. It is produced by one or more vacuum melting practices. This alloy is one of the strongest high-temperature alloys that can be formed and welded in sheet form; consequently, it is used widely for jet engine components. Other uses include turbine buckets, turbine wheels, rings and high-temperature fasteners and springs.
