Localized Corrosion Resistance of Mn-Substituted Austenitic Stainless Steels: Effect of Molybdenum and Chromium
Source abstract
Abstract
The pitting and crevice corrosion resistance of a number of Mn-substituted austenitic stainless steels has been determined quantitatively using temperature as a localized corrosion criterion. The go/no-go temperatures, the critical pitting temperature (CPT), and the crevice corrosion temperature (CCT) can be summarized by the equations CPT(C)=22+7×%Mo+5×(%Cr-18)and CCT(C)=-(20±5)+11×%Mo+3.5×(%Cr-18)for Mn-substituted austenitic stainless steels over the composition range 0 to 5% Mo and 18 to 22% Cr. The resistance to localized corrosion of these Cr-Ni-Mn-Mo alloys is compared with that of Cr-Ni-Mo austenitic stainless steels.
