Abstract
The oxidation of an austenitic steel containing 18% chromium and 12.3% manganese at 800‐1000°C in air occurs at a slower rate than that of a steel containing 9.5% chromium and 17.5% manganese. However, the rate of corrosion of this 18% chromium alloy is still large in comparison with the case of formation of a continuous chromia scale at the base of the scale layer. This result is attributed to the negative effect of the manganese on the thermodynamic stability of Cr2O3.Keywords
