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.INCOLOY Alloy 925 is an age-hardenable nickel-iron-chromium alloy. It provides high strength at temperatures up to 1000 F (540 C). It was developed for use in oil-production tubular products, tool joints, and equipment for surface and down-hole hardware for intermediate sour-gas wells. It is recommended for a number of other applications where resistance to general corrosion and pitting are required.
