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.Bethlehem Lukens Plate (BLP) C1119/C1144 Modified steels are resulfurized carbon steels containing nominally 1.15% Mn and 0.20 to 0.33% S to provide a free-machining steel. They are recommended especially for high-production automatic machining. They have relatively low hardenability. Their ductility and toughness are reasonably good in the longitudinal direction, but they tend to be low in the transverse direction. The many uses include mining equipment, bushings, bolts, and gears.
