| 摘 要： | 通过CCT曲线测定和热处理正交试验,研究了890～930℃25～45 min淬火和570～610℃50～80min回火参数对25MnV钢(%:0.25～0.30C、1.50～1.80Mn、0.06～0.15V)245 mm×12 mm管组织和力学性能的影响。结果表明,采用910℃35 min水淬+590℃65 min回火,套管的综合力学性能最佳:屈服强度878～906MPa,抗拉强度923～963 MPa,伸长率16.6%～17.4%,满足标准要求。

| Abstract: | Effect of parameters of quenching at 890 ?930 ℃ for 25 ~45 min and tempering at 570 ~610 ℃ for 50 ? 80 min on structure and mechanical properties of 245 mm x 12 mm tube of steel 25MnV (% : 0. 25 ?0. 30C, 1. 50 ~ 1. 80Mn, 0. 06 ~0. 15V) has been studied by measured CCT curves and orthogonal test of heat treatment. Results show that with austenizing at 910 °C for 35 min, water quenching, and tempering at 590 ℃ for 65 min, the comprehensive mechanical properties of casing tube are optimum i. e. yield strength 878 ~906 MPa, tensile strength 923 ~ 963 MPa and elongation 16. 6% ~ 17. 4% to meet the standard requirement. |
