摘　　要：运用均匀设计方法,通过改变H2S浓度、Cl-浓度、pH值和温度等溶液介质参数,对换热器管束用钢08Cr2A1Mo在湿H2S环境中进行慢应变速率拉伸应力腐蚀试验。研究了各参数对08Cr2A1Mo钢应力腐蚀开裂的影响规律,通过扫描电镜分析试样断口的微观形貌,确定其应力腐蚀敏感性,并根据试验结果计算在各试验环境下的应力腐蚀敏感性指数,运用回归分析软件,建立了08Cr2AlMo钢应力腐蚀敏感指数与试验介质参数之间关系的交互型数学模型。Based on the uniformity design method, the SSRT of heat exchangers tube steel 08Cr2A1Mo in different eoncentration of H2 S, concentration of Cl - , pH and temperature were tested. After analysed the microcosmic morphology by SEM, determined the nature of stress corrosion sensitivity and calculated the stress corrosion sensitivity index in different examination environment. Based on the regression analysis software, the intereross mathematics model of stress corrosion sensitivity index of 08Cr2A1Mo steel and medium parameters （concentration of H2S, concentration of Cl- , pH and temperature）were established.
