Influence of heat treatment on the corrosion of steels in CCS environment
- To predict the reliability and safety during the injection of compressed emission gasses - mainly containing CO2 - into deep geologica! layers (CCS-technoIogy, Carbon Capture and Storage), the influence of heat treatment on pit corrosion needs to be considered. In laboratory Experiments different heat treated steeis used as injection pipe with 13% Chromium and 0.46% Carbon (X46CrI3, 1.4034) and 0.2% Carbon (X20Crl3. 1.4021) as well as 16% Chromium Steel XöCrNiCuNb 16-4 (1.4542) were tested. The samples were exposed up to 1 year to the distinct synthetic aquifer environment saturated with technical CO2 at a flow rate of 3 l/h. The corrosion rate generally does not exceed 0.03 mm/year. Pits with maximum pit heights around 300 µm were obtained for hardened X20Crl3 with martensitic microstructure. The least amount of pits is found on X46Crl3. The higher carbon content in, X46Crl3 (0.46% C), results in a lower amount ofpits compared to X20Crl3 (0.20%).
