Abstract

The amount of hydrogen dissolved into Fe-10Cr-0.08C-0-0.03S (mass%) steels during the steam oxidation at 923 K was measured by thermal desorption spectroscopy (TDS). The amount of dissolved hydrogen was found to be dependent largely on the steam oxidation resistance of the steels. In other words, it was much smaller in the sulfur-doped steels with good oxidation resistance than in the sulfur-free steels with poor oxidation resistance. Thus, we suggest that the hydrogen dissolution is one of the most important factors to understand the steam oxidation resistance of the steels.
