6. ASTM 5140 Steel Heat TreatHeat to 680-720℃, cool slowly. This will produce a maximum 5140 hardness of 241HB (Brinell hardness).
Temperature: 840-880℃.
Harden from a temperature of 820-850, 830-860℃ followed by water or oil quenching.
Tempering temperature: 540-680℃.
7. Applications of AISI Grade 5140AISI 5140 steel can be used for low and moderately stressed parts for vehicles, engines and machines where hard, wear resisting surface is needed. Hardness as surface hardened about 54 HRC. SAE 5140 steels can also be for marine engineering industry, chemical processing plants, boiler & pressure vessels, nuclear power plants etc.
