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.
LA SALLE SERIES 83-420 is a low-carbon, bismuth-bearing, free-machining, cold-finished steel. It is the fastest machining screw stock available anywhere and does not contain lead, tellurium or selenium. Its excellent machinability is achieved by the addition of a special bismuth (atomic number 83) alloy; its nominal machining speed is 420 sfm (surface feet minute). Series 83-420 drastically reduces friction during machining and the chips break clean and small. This steel machines to a fine satin finish, can be carburized and performs well in cold-working operations such as roll threading, crimping, swaging and peening. It is recommended for automatic screw-machine operations.
