Abstract：In order to investigate the oxidation behavior of low Cr element content steel under water vapor conditions, a thermogravimetric analyzer (TGA) was used to carry out high-temperature oxidation experiments for 5Cr and 10Cr steel in a water vapor atmosphere. The mechanism of surface oxidation of low Cr content steel under water vapor atmosphere was studied by the metallographic microscope and XRD. The results show that the existence of water vapor on the surface of the matrix will produce holes and cracks, which becomes a favorable channel for the internal diffusion of water vapor. With the increase of chromium content, the higher the required temperature of the transformation from linear law to parabola law. The iron oxide layer of the sample is composed of the outer oxide layer and the inner oxide layer. The outer oxide layer is mainly Fe2O3 and Fe3O4, the inner oxide layer contains a large amount of Cr oxides. When the oxidation temperature is above 1 000 ℃, the weight gain of the two sheets of steel is close, mainly because the Cr elements in the steel are oxidized to form Cr2(OH)2 and Cr (OH)3, which results in the failure of the oxidation resistance of the inner layer.
