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.AISI 1552 is a medium-carbon steel that may be used in the hot-rolled, annealed, normalized, cold-worked or liquid-quenched-and-tempered condition for a variety of applications. It has a high manganese content (1.20-1.50%) to provide increased hardenability which is reflected in all uses and gives increased strength and hardness in many of its applications.
