Tailoring oxidation resistance of Super304H by controlling Mn content
Source abstract
Abstract
Abstract The effects of Mn on oxidation resistance of Fe-18Cr-8.5Ni-3.5Cu-0.5Nb-0.1C-0.1 N-(0.08–2.05 wt%)Mn alloys were investigated by isothermal oxidation in ambient air at 700 °C for up to 8 weeks. The Mn addition up to 0.44 wt% increased the oxidation resistance, but further addition decreased it, thus the best oxidation resistance was obtained in the alloy with 0.44 wt% Mn. Mn promoted the internal oxidation and changed the Mn and Cr concentrations of the inner oxide layer. The best oxidation resistance of the alloy with 0.44 wt% Mn was attributed to the improved protectiveness of the inner oxide layer having the highest Cr content.
