Local Corrosion of Martensitic Stainless Steels during Exposure to Saline Aquifer Water and CO2 Environment

Anja Pfennig and Axel Kranzmann
Abstract—Carbon Capture and Storage (CCS) is well acknowledged to mitigate climate change. Therefore, pipe steels suitable for CCS technology require resistance against the corrosive environment of a potential CCS-site, e.g. heat, pressure, salinity of the aquifer, CO2-partial pressure. Samples of different mild and high alloyed stainless injection-pipe steels partially heat treated: 42CrMo4, X20Cr13, X46Cr13, X35CrMo4 as well as X5CrNiCuNb16-4 were kept at T=60 °C and ambient pressure as well as p=100 bar for 700 h - 8000 h in a CO2-saturated synthetic aquifer environment similar to possible geological on-shore CCS-sites in the northern German Basin. Main corrosion products analysed on pits are FeCO3 and FeOOH. The carbon content does not show significant influence on the pitting behaviour. Generally, higher chromium content results in better corrosion resistance. Although X35CrMo17-1 and X5CrNiCuNb16-4 show low surface corrosion rates, their resistance against local corrosion in CCS environment is not significantly better compared to the much less costly steels X20Cr13 and X46Cr13.

Index Terms—Corrosion, CCS, carbon storage, aquifer, heat treatment, fatigue, endurance limit.
