In this study, the susceptibility of grade X80 pipeline steels to stress corrosion cracking (SCC) was investigated under near-neutral pH conditions and compared to that of grade X52 steel. Two grades of X80 were manufactured using the Thermo-Mechanical Controlled Process, whereas one grade of X52 was produced through Controlled Rolling. SCC properties were evaluated by cyclic loading tensile tests in NS4 solution that simulated a typical environment for SCC under cathodic protection. Grade X80 was found to have almost the same susceptibility to SCC as grade X52, when the former was tested under higher applied stress.

Keywords: Stress corrosion cracking, pipeline, hydrogen.
