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.TECHALLOY Alloy 625 is a nonmagnetic nickel-base alloy with excellent resistance to corrosion and oxidation. It has outstanding strength and toughness from cryogenic temperatures to 2000 F. It also has exceptionally high fatigue strength and is resistant to chloride-ion stress-corrosion cracking. It has a wide range of applications among which are aerospace components, specialized sea-water equipment and nuclear power equipment.
