一般情况下奥氏体不锈钢具有良好的耐腐蚀性,但在特殊的工况条件下,也会发生应力腐蚀现象,给工程带来极大的安全隐患。论述了奥氏体不锈钢应力腐蚀发生的条件、腐蚀的机理及防护措施,为解决奥氏体不锈钢应力腐蚀失效的问题提供了依据。
Under normal circumstances austenitic stainless steel has good corrosion resistance, but in special conditions, stress corrosion will occur, to bring great safety hazards to the project. The conditions of stress corrosion, the mechanism of corrosion and protective measures of austenitic stainless steel are discussed. It provides the basis for solving the problem of stress corrosion failure of austenitic stainless steel.
