EFFECTS OF A SMALL QUANTITY OF METAL IONS ON THE STRESS CORROSION CREAKING OF AUSTENITIC STAINLESS STEEL IN SIMULATED CONCENTRATED-BRINE

1. IntroductionConventional austenitic stainless steel (SS) such as type-304SS and type-316SS are widely used for the structural materials of salt production facilities. The austenitic stainless steel shows an excellent resistance to uniform corrosion even in highly-concentrated chloride solutions, if their pH are kept within near-neutral or alkaline range. However, it has a weakness that rather susceptible to localized corrosion such as pitting, stress corrosion creaking (SCC) and crevice corrosion in the chloride solutions. Among these variety forms of localized corrosion, SCC might be the most concerned form for practicing plant engineers, because in general, SCC propagates at higher rate than the other forms of localized corrosion, and easily cause a leakage of a process solution.
