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.NICKEL VAC X-750 is a precipitation hardenable nickel-alloy with high creep-rupture strength up to 1500 F(816 C) and excellent oxidation and corrosion resistance up to 1800 F(982 C). It is produced by vacuum induction melting followed by either vacuum arc or electroslag remelting.
