SCC Initiation for X80 Pipeline Steel Under AC Application in High pH Solution

摘要：

　　Stress corrosion cracking(SCC)behavior of U-bend samples of X80 steel under AC application was investigated in high pH solution by scanning electron microscopy(SEM)and macroscopic observation.The results show that AC application enhances the corrosion of X80 steel,and results in the occurrence of pitting corrosion.With the increasing AC current density,the corrosion degree of steel increases and the pits become more apparent.Pitting corrosion induces and facilitates the crack initiation,and thus increases the SCC susceptibility of the steel.
