Weight loss measurements and stress corrosion cracking (SCC) tests were performed on AISI 304 stainless steel (SS) in sulfuric acid solutions with chloride, bromide, or iodide at different potentials near the corrosion potential and at different concentrations of each halide. Contour maps of dissolution rates from the weight loss reveal the role of the halide ions in dissolution near the corrosion potentials. For all of the halide species, the SCC regions correspond to a dissolution rate that is lower than the crack propagation rates.
