The corrosion behavior of the Inconel X-750 alloy was investigated for its potential application under a Cl<sub>2</sub>-O<sub>2</sub> mixed gas flow in an Ar atmosphere. The corrosion rate was found to be negligible at temperatures up to 400℃ under a flow rate of 30 mL·min<sup>-1</sup> Cl<sub>2</sub> + 170 mL·min<sup>-1</sup> Ar, whereas an exponential increase was observed in the corrosion rate at temperatures greater than 500℃. The suppression of the corrosion reaction due to the presence of O<sub>2</sub> was verified experimentally at flow rates of 30 mL·min<sup>-1</sup> Cl<sub>2</sub> (4.96 g·m<sup>-2</sup>·h<sup>-1</sup>), 20 mL·min<sup>-1</sup> Cl<sub>2</sub> + 10 mL·min<sup>-1</sup> O<sub>2</sub> (2.02 g·m<sup>-2</sup> ·h<sup>-1</sup>), and 10 mL·min<sup>-1</sup> Cl<sub>2</sub> + 20 mL·min<sup>-1</sup> O<sub>2</sub> (1.34 g·m<sup>-2</sup>·h<sup>-1</sup>) under a constant Ar flow rate of 170 mL·min<sup>-1</sup> at 600℃ for 8 h. The surface morphology analysis results revealed that porous surfaces with tunnel-type holes were produced under the Cl<sub>2</sub>-O<sub>2</sub> mixed-gas condition. Furthermore, the effects of the Cl<sub>2</sub> flow rate on the corrosion rate were investigated, indicating that its impact was negligible within the range of 5-30 mL·min<sup>-1</sup> Cl<sub>2</sub> at 600℃.
