Corrosion is a surface phenomenon, which is defined as the deterioration of a material due to chemical and/ or electrochemical reactions. The continued interest in understanding corrosion phenomena and devising mitigation methods stems from the potential influence corrosion has on infrastructural damage across diverse industries. The most prevalent forms of corrosion encountered in the oil and gas industry are referred to as sweet and sour, corresponding to aqueous CO₂ and H₂S environments, respectively. The presence of an aqueous phase in these environments leads to the formation of a weak acid which is understood to be detrimental to the service life of carbon steel pipelines, when not properly mitigated.

UNS S83071 is a recently developed super duplex stainless steel with the composition 30Cr-7Ni-3.5Mo-N, optimized for general corrosion resistance. Previously presented data have shown that UNS S83071 has excellent acid corrosion resistance as well as excellent resistance to pitting and crevice corrosion. Furthermore, the grade has very high mechanical strength with good microstructure stability and weldability. This paper presents new data from general corrosion testing of UNS S83071 in various acid and caustic environments, including formic acid, nitric acid, phosphoric acid, sodium hydroxide, and others. The results show that UNS S83071 has excellent acid and caustic general corrosion resistance, demonstrating the suitability of the grade in several corrosive environments. UNS S83071 is a good candidate material for applications within chemical industry, and the presented data can assist in material selection e.g. for heat exchangers or equipment used in acid or caustic production plants.
