The　electrochemical　characteristics　and　stress　corrosion　behavior　of　316L　stainless　steel　in　the　borate　solution　with　different　pH　were　investigated　through　electrochemical　measurements,　slow　strain　rate　tension　(SSRT)　tests　and　immersion　experiments.　The　electrochemical　measurement　results　indicated　that　borate　solution　will　facilitate　the　passivation　film　deformation　on　the　surface　of　316L　stainless　steel,　and　the　corrosion　resistance　of　316L　stainless　steel　decreased　with　the　increased　of　pH.　While　the　pitting　corrosion　of　316L　stainless　steel　prone　to　occurred　in　the　borate　solution　with　the　value　of　pH　was　11.　At　the　same　immersion　time,　the　number　of　corrosion　pits　increased　with　the　pH.　Furthermore,　the　stress　corrosion　cracking　(SCC)　susceptibility　of　316L　stainless　steel　was　tested　by　SSRT,　and　suggested　that　higher　pH　leads　to　more　sensitive,　and　tensile　fracture　morphology　showed　the　characteristic　of　ductile　fracture　when　pH　was　7.
