The ASTM T92 steel was corroded at and at 1 atm of gas. The formed scales were thick and fragile. They consisted primarily of the outer FeS scale and the inner (FeS, )-mixed scale containing a small amount of the scale. This indicated that corrosion occurred mainly via sulfidation rather than oxidation due to the gas. Since FeS was present throughout the whole scale, T92 steel was non-protective, displaying high corrosion rates.
