摘要
采用化学分析、金相检验和断口扫描等方法对不锈钢开裂的原因进行分析。结果表明,钢管表面氯离子的富集,引起了钢管承受张应力部位应力腐蚀开裂。
Chemical composition analysis,microstructure examination and fracture analysis were conducted to clarify reasons for crack of stainless steel.The results show that: the crack of stainless tube is caused by the stress corrosion at the tension stress side of the tube,which resulted from accumulation of Cl on surface of the tube.
