摘要:
针对制氢装置造气区00Cr19Ni10不锈钢管件的外表面开裂现象，采用宏观形貌分析、化学成分分析、拉伸试验、金相显微组织分析、断口分析以及EDS 能谱成分分析等方法，对不锈钢管件裂纹产生原因进行了分析。从介质、材料和应力3个因素进行了不锈钢管件开裂机理分析，认为不锈钢管件开裂系氯离子应力腐蚀引起。对今后制氢装置造气区不锈钢管线的安全运行提出了建议。
Abstract:
Macromorphology analysis，chemical component canalysis，tensile test,metallographic micro-structure analysis，fracture analysis and EDS spectrum analysis have been carried out on the cracks in stainless steel 00Cr19Ni10 fittings in the gas production area of hydrogen plant. The cracking mechanism of stainless steel pipe fittings was analyzed from three factors of medium，material and stress，and it is believed that the cracking of pipe fittings is caused by chloride ion stress corrosion. Suggestions were proposed for the safe operation of stainless steel pipelines in the gas production area of hydrogen plants.
