The weldable super 13Cr stainless steel was investigated because of the application for flow line in CO2 environments with a little amount of H2S. TIG welding in the condition of no post weld heat treatment(PWHT) was used as the welding technique. The lowering of C content less than 0.01 mass% in the weldable steel was decreased a maximum hardness in the heat-affected zone(HAZ) and mitigated the sulfide stress cracking(SSC) susceptibility. The increasing of Mo content from 2.0mass% of the super 13Cr stainless steel OCTG(0.02C-12Cr-5.5Ni-2Mo) to 2.5mass% was improved SSC resistance in the HAZ. Based on these results, the weldable super 13Cr stainless steel which consisted of 0.007C- 12Cr-6Ni-2.5Mo-Ti has been developed. The welded-joint with the yield strength of 550 MPa(80ksi) and enough corrosion resistance was completed by using the welding material of super duplex stainless steel w-hlch had 25 Cr-9Ni-3Mo-2W-0.3N. The corrosion resistance to SSC at room temperatures and localized-corrosion at elevated temperatures of the welded-joint was the same as that the super 13Cr stainless steel OCTG. The improvement effect of the corrosion resistance by means of Mo addition was discussed based on the stability of Cr oxide passive film, the analysis results of the surface film formed in the CO2 environment containing H2S, and calculated-volubility of oxides, FeCO3 and sulfides in that environment. It was clarified that Mo assisted the formation of the Cr oxide passive film in the inner layer of the surface film and the formation of MO sulfide in the outer layer.
