摘　　要：在Cr-Ni-Mo-V高强韧钢的传统生产中均保留一定量的硅和锰,对钢的力学性能造成影响,针对这一情况,研究不同Si、Mn含量对Cr-Ni-Mo-V高强韧钢屈服强度、低温冲击功的影响。结果表明:Si和Mn对屈服强度没有明显贡献;提高Mn含量显著增加钢性能的分散度,提高Si含量则显著降低钢的低温冲击功。Certain amount of silicon and manganese are retained in the traditional production of Cr-Ni-Mo-V high strength and toughness steel,which will affect the mechanical properties of steel. The effect of different Si and Mn contents on yield strength and low temperature impact energy of Cr-Ni-Mo-V steel was studied. The results show that both Si and Mn have no obvious contribution to yield strength. The low temperature impact energy decreases with increasing Si content,and the dispersion degree of steel properties significantly increases with increasing Mn content.
