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 1151 is a resulfurized carbon steel containing nominally 0.85% manganese and a range of 0.08-0.13% sulfur to make it free machining. Its ductility and toughness are reasonably good in the longitudinal direction but are low in the transverse direction. It is recommended highly for high-production automatic machine products. Its uses include axles and shafts, spindles, gears, bolts and bushings.
