摘要
The ASTM T92 steel was corroded at 600 degrees C and 800 degrees C at 1 atm of N-2/3.1% H2O/2.42% H2S-mixed gas. The formed scales were thick and fragile. They consisted primarily of the outer FeS scale and the inner (FeS, FeCr2S4)-mixed scale containing a small amount of the Cr2O3 scale. This indicated that corrosion occurred mainly via sulfidation rather than oxidation due to the H2S gas. Since FeS was present throughout the whole scale, T92 steel was non-protective, displaying high corrosion rates.
