Short summary
Stainless steel was exposed to highly saline brines under anoxic and elevated temperature conditions. Samples were analyzed by various techniques in order to identify the nature of the secondary phases present in the corrosion layer forming at the steel–brine interface. Outcomes suggest that the corrosion layer has duplex structure, with an inner layer mostly of chromium (hydr)oxides and an outer layer made of iron- and nickel-based spinel compounds with admixed nickel (hydr)oxides.
