浅析定期检验中发现的两起不锈钢应力腐蚀问题

Causes Analysis of Two Failures in View of Stress Corrosion Occurred in Stainless Steel Found in Period Inspection

本文通过两起在用压力容器定期检验中发现的不锈钢应力腐蚀问题，分析了不锈钢应力腐蚀产生的原因，阐述了如何在压力容器定期检验中对有应力腐蚀倾向的容器作出判断。

In this paper, through two failures caused by stress corrosion occurred in stainless steel found in the period inspection, the causes resulting in stress corrosion were analyzed. Then, it is explained how to determine the vessels in which there is the occurrence possibility of stress corrosion in period inspection.
