  • The corrosion resistance of 2205 duplex steel in non-inhibited methanesulphonic acid at elevated temperature
    Finšgar, Matjaž ; Jackson, Jennifer
    The corrosion behavior of 2205 duplex stainless steel in methanesulphonic acid (MSA) at elevated temperature was investigated. It was proposed that uninhibited MSA could be utilized in acidizing ... procedures in petroleum wells constructed of 22Cr steel. The MSA was suggested as a substitute for conventional acids such as HCl which require the use of corrosion inhibitors. Corrosion rates of 22Cr steel in MSA solution with or without 24.13bar CO2 at 150°C after 6h of immersion were lower than what is often required by the petroleum industry. In conditions of H2S-containing MSA, significantly higher corrosion rates were observed.
