| Abstract: | Causes of failure in corrugation expansion joint of the vent gas cooler have been studied by the chemical analysis, optical microscopy and electron probe microanalysis. The results show that the early failure of the corrugation expansion joint was results from the stress corrosion cracking in the components. |

| Keywords: | corrugation expansion joint austenitic stainless steel stress corrosion |
