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.CANNON-MUSKEGON 8620 is a low-carbon triple-alloy steel capable of being carburized for wear resistance or heat treated for toughness. This steel is suitable for many engineering applications, and is used in large quantities in the investment casting industry for small parts. A higher silicon content is permissible in this steel than in AISI 8620 (wrought) alloy steel.
