Heat slowly to 650-700°C and thoroughly soak. Continue to heat the 51CrV4 steel to the final hardening temperature of 830-860°C and allow to be heated through. Oil quench. Tempering Temper immediately after hardening whilst tools are still hand warm. Re-heat to the tempering temperature then 51CrV4 Spring Steel Wire Rod, Round Bar Supplier TEMPERING Temper the 51CrV4 spring steel component immediately after quenching whilst tools are still hand warm. Re-heat to the tempering temperature then soak for one hour for every 25 millimeter of aggregate thickness (2 hours minimum) cool in air. For most applications tempering of this grade will be between 400-600°C.
Heat Treatment of steel grade 51CrV4. Heat treated :1631°C - 1165°C. Technological Curves of steel grade 51CrV4 51CrV4, 50CrV4, 1.8159, AISI 6150 - alloy steel51CrV4 / 1.8159, 58CrV4 / 1.8161, 59CrV4 / 1.2242 - specification and application. 50HF and DIN / EN equivalent alloys are structural alloys used in the engineering industry for heavy-duty spring components and oil hardened springs. The steel, unlike other carbon and alloy grades, is characterized by high hardness, low vulnerability to tempering, resistance for variable and heavy loads, and the ability to operate at elevated temperatures up to 300 . C67S, C75S, C85S, 65Mn4, 51CrV4 - spring steelchrome steels with additives of vanadium, manganese, molybdenum, and nickel (f.ex. 51CrV4 / 50HF, 50HS, 50HG, 60SGH) Carbon and alloy spring steels. The use of carbon steel is mainly for smaller and slightly less responsible spring elements. Its properties owes mainly to
Therefore, in order to ensure uniform grain size and no decarburization under the premise of complete austenitization, the best austenitizing temperature of 51CrV4 steel for good properties is 880°C.

In this sense, the article deals with the analysis of the results of experimental researches performed on steel 51CrV4. Experimental studies included responses of material at room and high temperatures as well as creep and fatigue behaviors of considered material. Responses of the material at room and high temperatures are displayed in the The temperature of 51CrV4 heat treatment - BBN SteelAs is known, 51CrV4 heat treatment performance and properties are good. 51CrV4 steel is usually used as spring steel. Under heat treatment conditions, 51CrV4 stEN 10089 Grade 51CrV4 quenched and tempered (+QT The steel 51CrV4 is used for hot formed springs, like high-stress vehicle leaf springs, spiral springs, torsion springs, coil springs as well as conical springs. High-temperature strength up to 300 °C (valve springs). Installation strength 1370 to 1720 MPa.
