Paper Title:
The Study of Stress Corrosion Crack in Heterogenic Welding Joints under Wet H2S
  Abstract

Stress corrosion cracking behavior of the six heterogenic welding joints was investigated under the 1300ppm; 2300ppm and saturated H2S concentration by slow strain rate tests and influencing factors of different H2S concentration and welding material are analyzed to the stress corrosion cracking. It is showed that stress corrosion cracking is more sensitive above 1300ppm H2S concentration. With the H2S concentration increase, the maximal stress, elongation and the time of rapture decrease on heterogenic welding joints 1Cr9Mo/45 and 0Cr18Ni9/1Cr9Mo. But they are not influenced to the joint 0Cr18Ni9/45. It is also concluded that replacement of A302 by Inconel182 can improve the corrosion resistance of 1Cr9Mo/45 but can not make any influence on the joints 0Cr18Ni9/45 and 0Cr18Ni9/1Cr9Mo
