Stress
corrosion cracking (SCC), common in austenitic stainless steels, is cracking
that occurs from the combination of stress and corrosion. Halides, in
particular chlorides, even in small amounts, are often associated with SCC.
The stress required includes the loading on the part and residual loads. The
heat affected zones of welds are often the site of SCC. SCC if often
intergranular, but it can also be transgranular.
