摘要：

Effects of Si and Mn contents on low-temperature toughness of 10 CrSiNiCu steel were studied in this paper.The results indicated that by properly lowering Si content and increasing Mn content,the strength is increased slightly,and the low-temperature toughness is improved markedly.When Si content decreased from 0.96%to 0.72%or 0.42 mass%,the 50%FATT dropped by 50℃ and the crack propagation energy in the process of impact increased obviously.The main reason for the improvement of toughness lies in the refining of grain size and the decreasing of the deteriorative effect of Si.
