摘要
对开裂失效的苯酚生产装置316L不锈钢塔塔身与塔板进行了外观检查,金相显微镜和扫描电子显微镜(SEM)观察了腐蚀开裂断口的形貌;X射线衍射技术和SEM分析了断口表面腐蚀产物的组成.结果表明,开裂失效的原因是氯离子导致的应力腐蚀开裂.
The appearance of failed stainless steel tower was examined by naked eye. The morphology of fracture on stainless steel was observed by optical-microscope and SEM. With help of x - ray spectrum and SEM, the element contents of the corrosion products on the fracture of the failed stainless steel were analyzed. The results indicted that the failure of stainless steel tower was attributed to SCC induced by Cl^-.
