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.Carlson alloys 317L, 317L 4, and 317L 4N are a family of superior corrosion-resistant austenitic stainless steels for service in severe envi-ronments. They maintain tensile and creep-rupture strength at elevated temperatures and are resistant to intergranular attack. These alloys are widely used in air-pollution control systems, pulp and paper plants, and chemical and petrochemical processing equipment.
