The susceptibility to stress corrosion cracking (SCC) of a sensitized, wrought type 304 (UNS S30400) stainless steel (SS) was assessed using the slow strain rate test (SSRT) technique under applied potential control. Data was obtained in lithium hydroxide (LiOH)-doped water with the addition of sulfate (SO{sub 4}{sup 2{minus}}) and/or chloride (Cl{sup {minus}}) ions. Test were performed over the temperature range from 50 C to 250 C. Intergranular SCC (IGSCC) was observed at temperatures from 150 C to 250 C. The effects of SO{sub 4}{sup 2{minus}} and Cl{sup {minus}} on the critical potential for IGSCC varied with temperature. Results were compared with literature data for IGSCC in pure water and in water containing other concentrations of dopants.
