TY - JOUR A1 - Pfennig, Anja A1 - Bäßler, Ralph T1 - Effect of CO2 on the stability of steels with 1% and 13% Cr in saline water JF - Corrosion science N2 - In engineering storage sites for Carbon Sequestration the CO2-induced corrosion of injection pipe steels is a relevant safety issue when emission gasses are compressed in deep geological layers. The reliability of the steels suitable for the geological onshore CCS-site (Carbon Capture and Storage) at Ketzin, Germany, is demonstrated in laboratory experiments in equivalent corrosive environment (T = 60 °C, p = 1–60 bar, aquifer water, CO2-flow rate of 3 L/h, 700–8000 h exposure time). Corrosion kinetics and microstructures were characterized using specimens of the heat treated steel 42CrMo4 (1.7225) used for casing, and specimens of the martensitic stainless injection-pipe steel X46Cr13 (1.4034).
