Abstract

Effect on sulfur in high temperature oxidation of Fe-20Cr-4Al alloy was studied for 18.0ks at 1273, 1373 and 1473K in oxygen. After oxidation at 1473K, adherence of oxide scales on Fe-20Cr-4Al (104ppm, 171ppm)S alloys was improved, however, oxides scales on Fe-20Cr-4Al (35ppm, 53ppm)S alloys spalled over the entire surface during cooling.
