This study compares the pitting resistance of two commercial 2205 duplex stainless steels. Counterintuitively, 2205-B, despite having a higher Pitting Resistance Equivalent Number and better passive film performance, exhibited a lower Critical Pitting Temperature. Through the potentiostatic pulse test and potentiostatic polarization, it was observed that 2205-B had a greater number of pitting initiation sites. Further investigation, using SEM inclusion statistics, revealed an increased presence of inclusions rich in calcium oxides as the underlying cause of this unexpected phenomenon.
