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.ALZ 301LN is an austenitic stainless steel with good formability and toughness and high mechanical properties. The higher carbon content of ALZ 301 has been replaced by nitrogen. This improves weldability by providing a higher resistance to sensitization and intergranular attack without lowering the strength.
