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 1019 is a carbon steel that combines good machinability, good hot and cold-workability, and good welding characteristics. It is used in the annealed, hot-worked, normalized, cold-worked or water-quenched-and-tempered condition for many automotive and metal-working applications. It may be used in the carburized condition or without carburizing.
