采用馒应变法对试样进行拉伸，并结合扫描电镜观察断口形貌，结果表明苯并咪唑类化合物（BMAT）对316L、2Cr13等不锈钢在5％HCl中的应力腐蚀有着良好的抑制作用。
Stretching method was used to stretch the specimen, and the morphology of fracture surface was observed by scanning electron microscope. The results showed that the benzimidazole compound (BMAT) had a good inhibition effect on stress corrosion of 316L, 2Cr13 and other stainless steel in 5% HCl.
