摘　　要：用原子吸收光谱分析了失效构件的化学成分 ,用 X射线衍射技术分析了腐蚀产物的相成分 ,用 SEM和金相显微镜分析了失效构件的断口形貌。分析结果表明 。The chemical composition of failed equipment was analyzed by atomic absorbing spectrum, the phase composition of corrosion products was analyzed by X ray diffraction, the fracture surface of failed equipment was examined by SEM and optical microscope. The results indicted that the failure of the stainless steel heat exchnager was due to SCC induced by Cl -
