Effect of Sigma Phase Precipitation on the Pitting Corrosion Mechanism of Duplex Stainless Steels

A new phenomenon of the pitting corrosion of three duplex stainless steels (DSSs), SAF2205, SAF2507 and Z3CN20.09M, induced by sigma phases is found and discussed. The pitting potential (Ep) of all three DSS specimens with smaller variations in the level of Cr content is remarkably higher than that...
