Oxidation behavior of low carbon steel was investigated in oxygen and water vapor using continuous thermogravimetric analysis (TGA). The effect of temperature, oxygen pressure, and water vapor content on the oxidation of the steel was studied. The morphology, composition, and microstructure of oxides formed in moist atmosphere were examined and analyzed by X‐ray diffraction (XRD), scanning electron microscope (SEM), and energy dispersive X‐ray analysis (EDX). The oxidation mechanism was discussed based on oxidation rate, oxide defects, and microstructure of the substrate and oxide layers.
