| 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. |
