Abstract
Alloy 29 for use in oil country tubular goods (OCTG) has been evaluated in sour environments. Stress corrosion cracking<br>(SCC) tests were conducted in various environments containing H2S, CO2, chloride ions and elemental sulfur at temperatures<br>between 140 and 160 °C. The results suggest that Alloy 29 is suitable for use in sour service, especially when high chloride<br>concentrations or elemental sulfur are present.
