dc.description.abstract	This paper reports the results of corrosion study for carbon steel, austenitic stainless steel, as well as titanium and nickel-based alloys which were tested in a simulated superheated geothermal environment (SSGE) in flow-through reactors to investigate the corrosion behaviour to aid in the future material selection for high temperature deep geothermal application. The testing fluid was superheated steam (T = 350 °C and P = 10 bars gauge) containing H2S, CO2 and HCl with condensate of pH = 3. The corrosion rate for all samples was negligible but carbon steel was prone to localized damage under a magnetite film with a sulphur rich sublayer.
dc.description.sponsorship	The authors would like to thank the Icelandic Research Fund (RANNÍS, grants no. 163108-051, 163108-052 and 163108-053) and Geothermal Research Group (GEORG) for funding this project. Employees at Innovation Center of Iceland (ICI) and employees at Grein Research for their technical assistance. The authors would also like to give gratitude to Nippon Steel Sumitomo Metals and TIMET for collaboration and providing samples for testing.
