This paper discusses corrosion behavior of Ti alloy containing Mo and Pd with high yield strength studied in S-containing H{sub 2}S-CO{sub 2}-Cl{sup {minus}} environment at elevated temperature. Ti alloys showed stress corrosion cracking (SCC) susceptibility in this environment, and the susceptibility largely depended on the yield strength of the alloys. It was clarified that the addition of Pd and/or the increase of Mo content in alloys was very effective for improvement of the SCC resistance. These Ti alloys coupled with carbon steel did not have hydrogen embrittlement susceptibility in NACE TM02-77 solution. Localized corrosion resistance of Ti alloys in S-containing sour environment was superior to that of Ni-base Alloy C276. The stability of TiO{sub 2} film in sour environment containing elemental sulfur was discussed on the basis of the potential-pH diagram of Ti-H{sub 2}O system at 200{degrees}C.
