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 1043 is a carbon steel that provides medium strength and medium toughness at relatively low cost. It can be used in the hot-rolled, normalized, oil-quenched-and-tempered or water-quenched-tempered condition for general-purpose construction and engineering. Its manganese content is a little higher than that of some of the other standard carbon steels with comparable carbon levels; this gives it slightly higher hardenability and hardness. It can be used for flame or induction-hardened parts; its relatively high manganese contributes to a strong core in these parts.
