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 1140 is resulfurized carbon steel. It contains nominally 0.85% manganese and a range of 0.08-0.13% sulfur to furnish tree machining characteristics. Its hardenability is relatively low. Its ductility and toughness are fairly good in the longitudinal direction but tend to be low in the transverse direction. It is recommended highly for high-production automatic-machine products. Among its many applications are splined shafts, screws, bolts, light-duty gears and tool holders.
