1Cr5Mo钢在硫化氢溶液中的慢应变应力腐蚀实验

Slow strain stress corrosion test of 1Cr5Mo steel in hydrogen sulfide solution

通过1Cr5Mo钢在湿硫化氢环境下的慢应变速率法应力腐蚀实验,分析了1Cr5Mo钢的硫化氢应力腐蚀敏感性以及其敏感性与硫化氢浓度的关系。并对试样微观断口形貌进行了扫描电镜分析。结果表明,随着硫化氢浓度的增加,1Cr5Mo钢的应力腐蚀性增强。

Through stress corrosion test using slow strain rate method in wet sulfide service, this paper analyzed the stress corrosion susceptibility of 1Cr5Mo steel in hydrogen sulfide service and the relationship between the stress corrosion susceptibility of 1Cr5Mo steel in hydrogen sulfide service and the hydrogen sulfide concentration. The micro-fracture appearance of sample was analyzed using scanning electron microscopy. Results showed that the stress corrosion of 1Cr5Mo is enhanced with the increasing of hydrogen sulfide concentration steel in hydrogen sulfide service.
