Stress corrosion cracking (SCC) is the growth of cracks in a corrosive environment. It can lead to unexpected sudden failure of normally ductile metals subjected to a tensile stress, especially at elevated temperatures.he chemical environment that causes stress corrosion cracking for a given alloy is often one which is otherwise only mildly corrosive to that metal. Hence, metal parts with severe SCC can appear bright and shiny, while being filled with microscopic cracks.
