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 X-750 is a precipitation-hardenable nickel-base alloy that is highly resistant to chemical corrosion and oxidation and has excellent stress-rupture and creep properties at temperatures up to 1500 F after suitable heat treatment.
