Abstract: The experiment of commercial heat treatment process for 82 mm plate of steel 14Cr1MoR (0. 15C- 1.48Cr- 0.57Mo)has been carried out at Wuyang Iron and Steel. The test results showed that heat- treated with 9℃/min heating up speed, austenite conditioning at 930 ℃ for 2.4 min/mm,water quenching at 870 ℃,and tempering at 680 ℃ for 3.0 min/mm, air cooling,the structure of steel was sorbite, of which the ambient tensile strength was 590～650 MPa, yield strength 445～485 MPa,elongation 27%～28%,reduction of area 73%～75%,cross impact energy 173～212 J, and the Qo.z at 580℃ was 295～330 MPa. The properties of different parts of plate were uniform up to the requirement of stan- dard.

摘要： 在舞钢进行了82mm 厚14Cr1MoR(%:0. 15C,1.48Cr,0.57Mo)钢板的工业性热处理工艺试验。 试验结果表明，采用9℃/min速度加热，930℃奥氏体化2.4 min/mm,870℃水淬，680℃保温3.0 min/mm回火、 空冷、热处理后，钢的组织为索氏体，室温抗拉强度590～650 MPa,屈服强度445～485 MPa,延伸率27%~28%,断面收缩率73%～75%,20℃横向冲击功173～212 J,580℃co₂为295～330 MPa。钢板各部分性能均匀，满足标准要求。
