In　order　to　study　the　anti-slip　behavior　in　slip　bolt　joints　with　stainless　steel,　give　reference　to　the　use　of　bolted　connection　in　engineering　as　well　as　the　stainless　steel　code　in　preparation,　the　slip　factor　in　bolted　connection　with　stainless　steel　was　obtained　through　experiment,　considering　three　types　of　bolts　(10.9,　A4-70,　A4-80)　and　four　kinds　of　surface　processing　method　(abrasion　blasting,　wire　drawing,　scoring,　non-processing).　Wire　drawing　exhibits　best　anti-slip　behavior,　then　scoring,　and　abrasion　blasting　last,　even　worse　than　non-processing.　10.9　and　A4-80　meet　the　requirements　of　preload　in　code　while　A4-70　fails,　which　means　that　the　torque　coefficient　of　A4-70　should　be　increased　in　the　further　study.　The　anti-slip　behavior　of　all　the　four　kinds　of　surface　processing　method　is　not　satisfactory,　so　that　new　processing　should　be　developed　for　the　widespread　use　of　frictional　bolts　in　stainless　steel.
