Abstract

Anodic dissolution of bulk (Mn, Cr, Fe)S was accelerated under applied stress. Despite the slight increase in transpassive dissolution of bulk Cr₂S₃ under stress, no difference in polarization behavior of bulk Ti₄C₂S₂ was observed under the stress and no-stress conditions. Under applied stress, a decrease in the pitting potential of the stainless steel with (Mn, Cr, Fe)S inclusions was confirmed. For the steel with CrS inclusions, pitting was initiated in the transpassive region, and the pitting potential decreased under applied stress. The pitting potential of the stainless steel with Ti₄C₂S₂ inclusions did not change under the stress and no-stress conditions.
