Abstract

Slow strain rate tests of cold-worked X-52 carbon (C) steel showed stress corrosion cracking (SCC) could be induced in dilute aqueous sulfate solutions at 50°C. The crack growth rate was of the same order of magnitude reported previously for carbonated solutions. Cracking susceptibility increased for potentials more anodic and more cathodic than the corrosion potential (E_corr) measured in deaerated solution. Transgranular cracking was observed in pH 6.2 solutions and at E_corr in pH 8 solutions.
