Abstract

Abstract Stow strain rate (SSR) tests were carried out on creviced specimens of austenitic stainless steels (SS) using mild anodic galvanostatic polarization, which maintained the potential just above the repassivation potential (ER) for crevice corrosion regardless of variations in ER with time. Various problems were encountered, such as gradual opening of the crevice, but these mainly resulted from use of the SSR test. The galvanostatic method was simpler than painstaking determination of the limiting value of ER followed by potentiostatic testing just above this potential.
