Abstract

In this paper, mechanical performance test, slow strain rate test (SSRT) and optical microscopy analysis were employed in studying the effect of carbon migration on sulfide stress corrosion cracking (SSCC) behaviors of Cr5Mo/A302/0Cr18Ni9 dissimilar joints. The results showed that the resistance to SSCC of this joint improved first then decline after 98h aging treatments. Optical microscopy analysis showed fracture located in coarse grain heat-affected zone (HAZ) of as-welded joint, while in the joints aged for 56h and 98h, the fracture position transferred from coarse grain zone of HAZ to carbon rich belt in welds.
