Abstract: The corrosion properties of stainless steel surfacing layer in chloride solution were investigated using immersion corrosion test. The morphology of corrosion surfaces was inspected by using metallography, scanning electron microscopy (SEM) and energy dispersive spectrum (EDS). The results indicate that no evidence of corrosion on stainless steel surfacing layer is found at room temperature condition. In the condition of high temperature, the pitting corrosion is induced by Cl^- and the corrosion increases with Cl^- concentration. The lack of Cr on the surface of metal is resulted from the high Cl^- concentration in crevice solution, then the crevice corrosion increases. The susceptibility to stress corrosion cracking (SCC) of the stainless steel increases with Cl^- concentration, and the SCC exhibits the character of intergranular crack.
