WebLiquids with low chloride content that would normally be considered harmless can cause chloride concentrations high enough to cause SCC. One example of where this can occur is underneath thermal insulation on piping. Standard austenitic grades, such as 4307 and 4404, are generally sensitive to chloride-induced stress corrosion cracking. WebAs a result, the chloride-induced SCC initiation was observed on the as–weld surface and the measured crack depth was 4 mm. There was no SCC on the surface-treated weld line ( Goto et al., 2013 ). Well-qualified surface treatment to remove the residual stress on the weld lines is necessary to prevent the chloride-induced SCC initiation of the ...
