本文主要介绍了15MnVNR压力容器用钢焊后热处理的热模拟研究结果。其结果表明,该钢在610℃进行焊后热处理时,具有再热脆化倾向。570±15℃是该钢最合适的焊后热处理工艺温度。
This article mainly introduces the thermal simulation of 15MnVNR pressure vessel steel after heat treatment. The results show that the steel has a tendency to reheat embrittlement when subjected to post-weld heat treatment at 610 ° C. 570 ± 15 ℃ is the most suitable post-weld heat treatment process temperature.
