Description: This low carbon steel has good case hardening properties. Although not classed as screw machine steel, at times it may be specified. This is an excellent steel for bending and cold forming, with good brazing and welding properties.
Application: Case hardened parts where core strength is not critical. Widely used in shafting applications.
