Abstract
ABSTRACTThe stress corrosion cracking (SCC) of Alloy 22 in concentrated ground waters was associated to the presence of bicarbonate and chloride ions in the water. SCC occurred when an anodic peak appeared in the polarization curve of Alloy 22. The aim of this work was to investigate further which element in Alloy 22 was responsible for the anodic peak and therefore SCC. Four alloys (22, 800H, 600 and 201) were mainly used for this study. It has been found that Alloy 22, 600 and 800H show anodic peaks; which are affected by chloride and temperature. It is likely that the anodic peak is associated to the presence of either chromium, molybdenum or both.
