摘　　要：针对石化特种设备中硫化氢(H2S)应力腐蚀问题现状,综合比较了国际权威机构NACE,EFC以及ISO发布的最新标准、规范,对H2S应力腐蚀的环境界定、试验方法、影响因素、应力腐蚀评价准则及对材料的要求等做了扼要的综述。同时对焊接残余应力的产生、测定方法、消除措施等进行了论述,列举了实际参与研究的发生应力腐蚀容器的实例及残余应力的影响。To understand the present status of the issue of H2S stress corrosion in petrochemical special equipment, an integrative comparison among the latest standards released from international authorities such as NACE, EFC and ISO is conducted in this paper. A compendious overview containing the environment definition, test method, influence factor, evaluation standard of stress corrosion and the material demand in H2 S stress corrosion issue is accomplished. Meanwhile, a discussion of the causation, test method and elimination measure of welding residual stress has also been done.
