摘　　要：研究了不同焊后消除应力热处理(SR处理)温度和SR处理次数对JFE-HITEN610U2L钢及其焊接接头力学性能的影响。结果表明,在560～600℃温度范围内进行两次SR处理(每次保温2h)是可行的;经3次580℃×2h SR处理后,其-50℃冲击吸收功仍较多地高出技术要求值。The effects of stress relief（SR） treatment at different temperature and several time on the mechanical properties of JFE-HITEN610U2L welded joint were studied.The results show that twice SR treatment can be carried out at 560 ～600 ℃.After SR at 580℃ × 2 h for three time,the impact toughness at-50 ℃ is much higher than that of technical requriment.
