摘要
新型Fe-Cr-Mo-V系热强耐蚀钢是一种新开发的具有高硬度,红硬性和一定耐腐蚀性的特种钢材。通过对淬火和回火试样的微观组织观察和硬度测试,研究了该钢种的热处理工艺。结果表明,该钢种的最佳热处理工艺为1 120℃水淬,560℃回火2 h,经该工艺处理后材料的拉伸强度为1 607 MPa、冲击功为8.2 J、断面收缩率为30.56%,伸长率为4.4%。
The Fe-Cr-Mo-V thermal strengthening and corrosion resistance steel is a newly developed special steel with has better mechanical properties and corrosion resistance. The heat treatment process of this steel was investigated through microstructure observation and hardness test with appropriate quenching and tempering. The results show that the optimum heat treatment process for the steel is water quenching at 1 120℃ and tempering at 560℃ for 2 h. After such processing, the tensile strength of the steel is 1 607 MPa,impact value is 8.2J, reduction of area is 30. 56% and elongation is 4. 4%.
