%X The stress corrosion cracking (SCC) behaviors of X70 pipeline steel in near-neutral pH solutions at different temperatures and applied potentials are studied with slow strain rate testing (SSRT). The results show that the cracking mode of X70 pipeline steel in near-neutral pH solutions is transgranular at different temperatures with the feature of quasi-cleavage. The susceptibility to SCC increases as the applied potential moved towards the cathodic direction. Hydrogen induced cracking (HIC) dominates the process. The value of pH decreases slightly with decreasing temperature of the solution, and the susceptibility to SCC increases.
