The effect of Ce addition on sensitized type 316 stainless steel's (SS), stress corrosion cracking (SCC) behavior in oxygenated pure water was investigated. The slow strain rate tests showed significant decrease of intergranular fracture morphology with addition of 0.01 wt% Ce to 316 SS whereas sensitized 316 SS without Ce addition failed with not less than 80% of the fracture surface showing intergranular cracking. The bulk mechanical and microstructural properties explained the intergranular SCC resistance due to addition of 0.01% Ce and the addition of small amount of Ce could affect the electronic properties of passive films.
