WebStress corrosion cracking (SCC) is the growth of crack formation in a corrosive environment. It can lead to unexpected and sudden failure of normally ductile metal alloys subjected to … Web(Polythionic acid SCC) True or False: SO2 is normal component of regenerator flue gas, as is water vapor. Therefore simply cooling the regenerator while it contains flue gas can result in water condensation, absorption of SO2 in the water, and formation of sulfurous acid which like polythionic acid. Can cause cracking. incirlik commissary
