Abstract
The influence of pre-oxidation on the corrosion resistance of the aust enitic steels AC 66 (Fe-32Ni-27Cr-0.07Ce) and Alloy 800H (Fe-32Ni-20Cr ) was studied in a sulphur-oxygen-carbon bearing atmosphere at 700 deg rees C. For AC 66 the corrosion resistance was significantly improved by preoxidation. whereas this effect was less marked for Alloy 800H. T his can be explained by a much better adherence of the preformed oxide scale for AC 66. The corrosion resistance was shown to decrease by su perimposed deformation which leads to deeply penetrating intergranular corrosion paths.
