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 8627 is an alloy steel of moderate-to-good hardenability for carburizing and other applications. When carburized, its core has good strength and toughness, and it is recommended for heavy-duty applications such as gears, shafts, cams, and machinery parts. Also, it can be used in the hot-rolled, normalized or water-quenched-and-tempered condition without carburizing.
