%X In the paper the analysis results of 29 failed 18\|8SS bellows for catalytic cracking device were summerized. The analysis was performed by means of various techniques including chemical analysis, metallography, SEM,SAM and ESCA. The results showed that near by 80% of the bellow failures resulted from stress corrosion crack (SCC) due to chlorine ion; The magnitude of residual stress resulted from improper design and installation, which limiled strongly the lifetime of the bellows service. The protective measures such as annealing for stress-relieving, surface modification and application of new alloy(FN) have been taken and outstanding economical benefit has been obtained.\=
