Fig.1. MnS inclusion induced pitting mechanism proposed by Ryan et al: (a) pitting mechan-ism without Cr-depleted zone around the MnS inclusion, (b) pitting mechanism with Cr-depleted zone around the MnS inclusion (Note: 1-chloride ion penetration; 2-sulfur shell generation; 3-pitting propagation; 4-Cr-depleted zone around MnS inclusion; 5-priority dissolution of Cr-depleted zone)
