High-Temperature Corrosion of Carbon Steel in Air, Ar/0.2%SO2, and N2/0.4%H2S Gases

Article Preview

Abstract:

Hot rolled mild steel was corroded in air, Ar/0.2%SO2 and N2/0.4%H2S gases for 20 and 50 h. The corrosion in air at 800 and 1000°C resulted in the formation of Fe2O3/Fe3O4/FeO layered scales from the surface. The corrosion in Ar/0.2%SO2 gases resulted in the formation of (FeS, Fe2O3, Fe3O4, FeO)-mixed scale at 800°C, and (Fe2O3, Fe3O4, FeO)/FeS layered scale at 1000°C. The corrosion in N2/0.4%H2S gases at 650 and 750°C led to the formation of (Fe2O3, Fe3O4, FeO)/FeS layered scales.
