The effects of temperature and applied potential on the intergranular stress corrosion cracking, IGSCC, susceptibility of sensitized SUS304 stainless steel in NaF aqueous solution have been investigated by using slow strain rate test, SSRT, based on the direct observation of crack generation and propagation during the test. It was found that the decrease in the maximum stress, which is usually used as a conventional SCC susceptibility index by SSRT, with increasing temperature was caused not only by the decrease in K'ISCC and crack generation time but also by the increase in crack growth rate and the number of cracks. The result of potential-controlled SSRT proved that the lowest maximum stress at 100 mVAg/AgCl was induced by the decrease in K'ISCC and crack generation time. In conclusion, crack generation is more important compared with crack propagation for deciding the IGSCC susceptibility of sensitized SUS304 stainless steel in NaF solution.
