Corrosion Resistant Alloys (CRAs) have been widely used in oil & gas process systems since the 1980s due to their excellent resistance towards uniform corrosion in aggressive environments such as seawater and produced water containing CO₂, organic acids and/or production chemicals. However, cases of localized corrosion in the form of pitting and crevice corrosion have regularly been observed. As an example, ISO⁽²⁾ 21457 limits the max. operating temperature to 20⁰C for 25 Cr super duplex stainless steel (UNS S32750/760) and 6-Mo austenittic stainless steels (UNS S31254) in chlorinated seawater systems, to avoid crevice corrosion.¹
