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.SAE 1023 is a carbon steel of relatively low manganese content (0.30-0.60%); therefore, its hardenability, hardness and strength are somewhat lower than that of steels of higher manganese content at comparable carbon levels. It has good machinability, good workability (hot or cold) and good weldability. It is used in the annealed, hot worked, normalized or water-quenched-and-tempered condition for many automotive and general industry applications. It may be used in the carburized condition or without carburizing.
