4140 hardened and tempered bar can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc 50.The black hot rolled surface will first require to be machined sufficiently to remove any decarburised layer otherwise less than satisfactory results will be obtained.Parts should be 4140 LPA Cold Drawn Steel Bar - Hot Rolled & Cold Drawn 4140 Annealed (LPA) Cold Drawn Steel Bar. Annealed, cold drawn 4140 steel bar is a medium carbon, chromium-molybdenum steel with high hardenability. It is softened from the mill structure, to a pearlite structure, prior to cold drawing. This improves the ductility and can help improve machinability.
Cold Working. AISI 4140 alloy steel can be cold worked using conventional methods in the annealed condition. Annealing. AISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace. Tempering. AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. AISI 4140 Alloy Steel (UNS G41400)However, the mechanical properties of this steel will be affected if it is welded in the heat-treated condition, and post-weld heat treatment should be performed. Heat Treatment AISI 4140 alloy steel is heated at 845°C (1550°F) followed by quenching in oil. ASTM1020 High Precise Cold Rolled Seamless Tube(id Our Company.
