试验研究了新型高强度弹簧钢60SiCrV7(%:0.54～0.65C

1.35～1.65Si

0.7～1.0Cr

0.1～0.2V)的淬、回火工艺对力学性能的影响

结果表明

经最佳热处理工艺920℃油淬

430～450℃回火后

钢的抗拉强度为1750MPa

屈服强度1440MPa

冲击功9J

具有高的疲劳寿命

可以满足高强度弹簧设计需求。

Abstract

The quenching and tempering process on mechanical properties of a new high strength spring steel 60SiCrV7 (0.54C~0.65C

1.35～1.65Si

0.7～1.0Cr

0.1～0.2V)has been tested the results showed that by optimum heat treatment process - oil quenched at 920 ℃ and tempered between 430 ℃ and 450 ℃

the tensile strength of steel was 1750 MPa

yield strength 1440 MPa and impact energy 9 J

the steel had high fatigue life able to meet the design requirement of high strength spring.
