Effect of copper on active dissolution and pitting corrosion of 25% Cr duplex stainless steels

Abstract:

Electrochemical studies were made of the influence of Cu on pitting behavior and active dissolution of 25% Cr duplex stainless steels (DSS) in chloride-containing neutral and acid solutions. Alloys with increased Cu content showed higher. pitting potentials (E-p) in 1 M hydrochloric acid (HCl) and 3.5% sodium chloride (NaCl) solutions. In HCl, the current density in the active stale also was lower for the Cu-containing alloys, However, the critical pitting temperature (CPT) in ferric chloride...
