Abstract The electrochemical behavior of sensitized, carburized, and mill-annealed alloy 600 (UNS N06600) was studied in hydrogenated, aerated, and high-temperature (250°C to 350°C) dilute aqueous solutions. In high-temperature water at high anodic potentials, the current density (CD) from carbide dissolution was higher than CD from matrix dissolution. In oxidizing environments, intergranular stress corrosion cracking propagated in alloy 600 by dissolution of continuous or semicontinuous carbides at the grain boundary, in sensitized and non-sensitized materials.
