Fe-2%Mn-0.5%Si alloys were corroded at 600, 700 and 800℃ for up to 70 h in 1 atm of N<sub>2</sub> gas, or 1 atm of N<sub>2</sub>/H<sub>2</sub>O-mixed gases, or 1 atm of N<sub>2</sub>/H<sub>2</sub>O/H<sub>2</sub>S-mixed gases. Oxidation prevailed in N<sub>2</sub> and N<sub>2</sub>/H<sub>2</sub>O gases, whereas sulfidation dominated in N<sub>2</sub>/H<sub>2</sub>O/H<sub>2</sub>S gases. The oxidation/sulfidation rates increased in the order of N2 gas, N<sub>2</sub>/H<sub>2</sub>O gases, and, much more seriously, N<sub>2</sub>/H<sub>2</sub>O/H<sub>2</sub>S gases. The base element of Fe oxidized to Fe<sub>2</sub>O<sub>3</sub> and Fe<sub>3</sub>O<sub>4</sub> in N<sub>2</sub> and N<sub>2</sub>/H<sub>2</sub>O gases, whereas it sulfidized to FeS in N<sub>2</sub>/H<sub>2</sub>O/H<sub>2</sub>S gases. The oxides or sulfides of Mn or Si were not detected from the XRD analyses, owing to their small amount or dissolution in FeS. Since FeS was present throughout the whole scale, the alloys were nonprotective in N<sub>2</sub>/H<sub>2</sub>O/H<sub>2</sub>S gases.
