THE EFFECT OF PREOXIDATION AND THE INFLUENCE OF DEFORMATION ON THE CORROSION BEHAVIOR OF 2 HEAT-RESISTANT STEELS IN A SULFUR-OXYGEN-CARBON BEARING ENVIRONMENT
Mf. Stroosnijder et al., THE EFFECT OF PREOXIDATION AND THE INFLUENCE OF DEFORMATION ON THE CORROSION BEHAVIOR OF 2 HEAT-RESISTANT STEELS IN A SULFUR-OXYGEN-CARBON BEARING ENVIRONMENT, Corrosion science, 36(2), 1994, pp. 207
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.
