Shot peened steel tubing made from 304HCu-grade austenitic stainless steel was exposed to temperatures of 600-750°C in three atmospheres: vacuum, deoxygenated atmospheric pressure steam and deoxygenated 70bar steam. The microstructural changes and oxide morphologies of the shot peened material were observed with SEM, TEM, microhardness testing and TKD mapping. An estimate of the lifetime of the shot peened microstructure in service conditions was made based on service temperature. MnCr2O4 spinel was observed on oxidized samples and the consequences of this are discussed.
