Abstract

The corrosion behaviour of the austenitic 32Ni-27Cr-0.07Ce steel AC 66 was studied at 700 C in various S-O-C bearing gases, simulating coal gasification environments, for exposure times up to 5000 h. It was found that relatively small variations in oxygen and sulphur activities can cause a significant change in corrosion behaviour, which varied between a more or less protective oxide scale and significant sulphidation. Deformation was observed to cause significant enhancement of corrosion, particularly along grain boundaries lying perpendicular to the stress axis.
