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.HIGH SULPHUR. This high carbon, vanadium alloyed steel has an addition of sulfur (.20-.25%) to aid in the machining of large bars. The material is produced by the rapid solidification process to eliminate normal sulfide stringers.
