摘　　要：利用正交试验法研究了碳、硅、锰、铬、钒对弹簧钢性能的影响。结果表明，随硅含量提高，钢的抗弹减性增加，含２％Ｓｉ是必要的；铬在一定程度上对抗弹减性不利；添加少量钒使钢的抗弹减性显著改善，且在４８０～５２０℃回火引起明显的析出硬化。通过验证试验提出的新型５０Ｓｉ２ＭｎＣｒＶ弹簧钢具有高的抗弹减性、充足的淬透性和良好综合性能，适合大截面汽车板簧设计与制作的要求。By means of orthogonal experiment design method, the effect of C, Si,Mn, Cr, V on the properties of spring steel have been studied in this paper Experimental results show that, with the increasing content of silicon, the sag resistance increases, so 2 % Si is necessary, chromium deteriorates sag resistance to some extent The addition of a small amount of vanadium is able to give the steel excellent sag resistance and obvious precipitation hardening in temperature 480520 is observed Based on the experimental results, a new type spring steel 50Si2MnCrV with better sag resistance and sufficient hardenability have been successfully developed, which is suitable for large plate springs
