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 1045 is a medium-carbon steel used in four conditions: hot rolled, normalized, oil quenched and tempered or water quenched and tempered. It is a general-purpose engineering and construction steel and provides medium strength and toughness at low cost. It is commonly used for flame- or induction-hardened parts.
