Effect of holding time on the corrosion potential of SS304

Effect of holding time on the corrosion potential of SS304

Stainless steels suffer from classical sensitization when encounter at certain temperature which results in precipitation of chromium carbide along grain boundary with simultaneous depletion of chromium from near grain boundaries. This study focused on corrosion potential test at different sensitiza...
