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 8622 is a low-carbon triple-alloy steel of moderate-to-good hardenability for carburizing and other applications. Its core is characterized by good strength and toughness. When carburized it is recommended for heavy-duty applications such as cams, gears, shafts and piston pins. It is suitable also for many engineering applications when normalized or quenched and tempered.
