The yield strength of the new 15Cr steel pipe was higher than 861 MPa (125 ksi), and good Charpy toughness was obtained in extremely low temperature condition. This material showed remarkably high strength even at high temperature of 200 degree C. The CO2 corrosion resistance was significantly improved so that the critical temperature for the developed pipe was more than 200 degree C at 15 MPa CO2 partial pressure. The superior corrosion resistance for revised the new 15Cr steel pipe was obtained by the higher amount of effective Cr in solution. In addition to this, the new 15Cr steel pipe showed good SSC resistance even in its high yield strength in the mildly sour environment. The good SSC resistance for this developed pipe was obtained by the good pitting resistance, induced from high Cr and Mo addition.
