研究了焊后热处理对 15CrMoR钢板性能的影响。结果表明焊后热处理工艺对 15CrMoR钢板强度指标影响不大 ,但能较大地降低钢板的低温冲击功 ,即提高了钢板的韧脆性转变温度
The effect of postweld heat treatment on the properties of 15CrMoR steel was investigated. The results show that the post-weld heat treatment process has little effect on the strength index of 15CrMoR steel but can greatly reduce the low-temperature impact energy of the steel, ie, increase the ductile-brittle transition temperature of the steel
