what is stress corrosion cracking
Stress corrosion cracking (SCC) is the growth of crack formation in a corrosive environment.It can lead to unexpected sudden failure of normally ductile metals subjected to a tensile stress, especially at elevated temperature in the case of metals.s one of the requirements for stress corrosion cracking is the presence of stress in the components, one method of control is to eliminate that stress, or at least reduce it below the threshold stress for SCC.
