CF-62钢制无水液氨球罐的应力腐蚀

Stress Corrosion of CF-62 Steel Spherical Tank in the Anhydrons Ammonia Enrironment

本文就某大型企业６５０ｍ ３ 无水液氨球罐开罐检查所发现的应力腐蚀问题，对ＣＦ－ ６２ 钢在无水液氨环境下抗应力腐蚀能力进行了探讨。

This paper analysis the crack defects found during the spherical tank opening inspection. The tank was made of CF-62 steel. The results show that CF-62 steel will cause stress corrosion under a certain stress level and in the anhydrous ammonia environment.
