Notes:
The high-temperature oxidation in air and steam at 923 K was examined withpure iron, Fe-10Cr and Fe-10Cr-0.08C (0~0.03)S steels. The amount of hydrogendissolved into samples during exposure to steam was measured with thermal desorptionspectroscopy (TDS). It was found that the amount of dissolved hydrogen was relatedclosely to the steam oxidation resistance of the steels. In case of pure iron, thethickness of the oxide scale formed in steam at 923 K for 360 ks was comparable to thatof the scale formed in air. On the other hand, in case of the Fe-Cr binary alloy and theternary ferritic steel, the oxide scale was much thicker in steam than in air. It wasfound that the amount of the dissolved hydrogen was much larger in both the binaryalloy and the ternary ferritic steel than in pure iron, and then it leads to the moreaccelerated oxidation rate in the ternary steels in steam
