Stress corrosion cracking susceptibility of carbon steel and decarburized steel was studied in 8.5 M sodium hydroxide at 100 °C. Potentiodynamic experiments were performed to determine the potential values to be applied in slow strain rate (ssr) experiments. Optical and scanning electron microcopy were used to investigate the surfaces of corroded samples. Severe intergranular stress corrosion cracking was observed on the carbon steel samples in comparison to the decarburized steel samples.
