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.

Allegheny Ludlum alloy 255 is a high-strength duplex stainless steel. It combines high mechanical strength, ductility, and hardness with excellent resistance to corrosion and erosion. Under most conditions of service, its corrosion resistance is superior to that of the fully austenitic AISI type 304, 316, and 317L stainless steels. Its many uses include marine scrubbers, desalination equipment, sulfuric acid production, wet phosphoric acid production, mild sour gas wells, urea production, and applications in the pulp and paper industry.
