To better understand the mechanism for stress corrosion cracking (SCC) the advanced analytical tools, including high-resolution scanning electron microscope (SEM), focus ion beam (FIB) and transmission electron microscope (TEM) were used. The complexity of stress corrosion cracking results from the dependence of SCC on composition of the steel, applied stress, water chemistry in the field, and ionic concentrations in the groundwater near the pipe surface, may all have an effect on crack initiation and propagation.
