摘　　要：某石化公司制氢装置材料为321不锈钢的弯头开裂导致介质泄漏。采用金相、电镜、能谱、化学分析等方法对裂纹处进行了分析。通过对应力分析、应力腐蚀环境的分析,判断弯头上裂纹是应力腐蚀开裂的结果。The cracking of elbow made of 321 stainless steel in hydrogen plant of a petrochemical company resulted in medium leakage. The crack was analyzed by means of metallography, electron microscope, energy spectrum and chemical analysis. Through the analysis of stress analysis and stress corrosion environment, it is concluded that the crack on the elbow is the result of stress corrosion cracking.
