Abstract：By regulating the quenching and tempering temperature of 52CrMoV4 spring steel,the optimum heat treatment temperature was researched and analyzed.The results show that the hardness value reaches its maximum at 880 ℃ and then decreases as the temperature rises and the plasticity of the steel decreases as the temperature rises.At the same time,the tempered troostite in spring steel is increased as rising of the tempering temperature,and resulting in increased plasticity of steel.According to the experimental data,the mechanical properties of spring steel reach the best when quenching temperature is at 880 ℃ and tempering temperature is at 380 ℃.Rockwell hardness test value is 52.1 HRC,yield strength test value is 1 722 MPa,tensile strength test value is 1 820 MPa,elongation after break test value is 10％.
