Welcome to BBN High Strength Steels Factory
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the S690QL EN 10025-6 high strength steel quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After S690QL EN 10025-6 high strength steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
40Cr steel is one of the most widely used steels for mechanical operations. The hardenability of this steel is outstanding, it can be hardened to Ф28 ~ 60mm when water quenching, and Ф15 ~ 40mm when oil quenching. In addition to quenching and tempering treatment, 40Cr steel is also suitable for cyanidation and high frequency quenching treatment. 40Cr steel has good cutting performance. When the hardness is 174 ~ 229HB, the relative machinability is 60%. The steel is suitable for making medium-sized plastic molds.
