Stress Corrosion Cracking Behavior of 304L Stainless Steel in Secondary Loop of PWR Environment

The effect of ammonia, ethanolamine, mixture of ammonia and ethanolamine on stress corrosion cracking (SCC) of 304 stainless steel in simulated secondary loop of PWR environment was investigated using slow strain rate tests (SSRT). And the fracture morphology of specimens was analyzed by scanning electron microscopy (SEM). The results showed that 304 stainless steel had similar susceptibility to SCC in different simulated solutions.
