An exposure test programme has been undertaken to investigate the localised corrosion resistance of Alloys 28, 825, G3 and 625 in two simulated sour gas environments at 150°C. The chloride levels in these test environments, containing 30 psi (0.21 MPa) H2S and 101 psi (0.70 MPa) CO2, were 150 ppm and 30,000 ppm. The general corrosion rate of each material was found to be negligible in each test. Alloy 825 alone was susceptible to minor pitting and crevice initiation in the 150 ppm chloride environment. Increasing the chloride level to 30,000 ppm resulted in more severe crevice attack of Alloy 825 and crevice corrosion of Alloy 28. Alloys G3 and 625 were not susceptible to localised corrosion in either test environment. The exposure tests were supported by complementary electrochemical polarisation curves in the low chloride environment. The curves did not exhibit clearly defined passive regions, which were masked by additional anodic current from the oxidation of H2S. Keywords: sour gas, corrosion resistant alloys, pitting, crevice corrosion, electrochemical testing

Test results for four alloys in six different sour environments are presented. Alloys 625, 825, 316L and carbon steel were testing in sour gas with varying exposure to moisture at 280°C. Corrosion rates for each alloy over a 30 day period are measured from mass and thickness changes.
