UNS1 C72900 has many applications in Oil & Gas exploration because of properties that include low friction, high wear resistance, non-magnetic, high strength and corrosion resistance. However, the specific sour corrosion phenomena of this copper alloy have not been extensively studied and clear corrosion and cracking usage limits have not yet been established. It is for these reasons that the alloy is not specifically listed in the materials recommendation for sucker rod pumps (NACE(2) MR01762), in NACE Publication 1F1923 or in ANSI(3)/NACE MR0175-2015 / ISO(4) 15156-34 (NACE MR0175). This is situation is not ideal, as end users are restricted in applicability by the absence of information, or exposed to risks when the alloys is utilized due to the same absence of information. This paper addresses some of the sour corrosion phenomena observed in laboratory testing as it related to the microstructural features of those specimens. This was investigated through a parametric study of varying temperature and levels of H2S and chloride. The end goal of this work was to increase the knowledge base about UNS C72900 and to associate some of the possible corrosion phenomena with the underlying metallurgy of the alloy(s).
