A decrease in Mn content reduced Mn-related oxide/sulfide inclusions and elevated the Cr2O3 content in the passive film, conferring better corrosion resistance of FeCrNiCoMnx. The XPS results revealed a competitive oxidation of Mn with Cr, which lowered the Cr2O3 content in the passive film. This leads to inferior corrosion resistances of FeCrNiCoMn, FeCrNiCoMn0.6, and an equivalent resistance of FeCrNiCoMn0.3, compared to 304 L stainless steel. ? 2021 Elsevier Ltd |
