Abstract
The cracking analysis of separator made of 304 stainless steel had been conducted by examining residual stress,testing mechanical performance and analyzing the microstructures. The results showed that the cracking was typical stress corrosion cracking. The cracking was induced by the sulfide in the working medium. The circumferential working stress may play a dominant role and the residual stress due to welding was also responsible for the cracking.
