Stainless Steel 317 Nuts And Bolts<\/strong>, which contain sufficient chromium to undergo passivation, forming an inert film of chromium oxide on the surface. Since iron oxide has lower density than Stainless Steel 317 Hex Head Bolts, the film expands and tends to flake and fall away. This layer prevents further corrosion by blocking oxygen diffusion to the surface of Stainless Steel 317 Hex Head Nuts and stops corrosion from spreading into the bulk of the metal.<\/span><\/p>\n<\/span><\/p>\nPassivation in Stainless Steel 317 Square Bolts occurs only if the proportion of chromium is high enough and oxygen is present in it. Resistance to corrosion and staining, low maintenance, and familiar lustre make Stainless Steel 317 Square Nuts an ideal material for many applications. Stainless Steel 317 Eye Bolts is used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment (for example, in sugar refineries).<\/span><\/p>\nStorage tanks and tankers used to transport orange juice and other food are often made of Stainless Steel 317 Eye Nuts, because of its corrosion resistance. High oxidation resistance of Stainless Steel 317 U-Bolts in air at ambient temperature is normally achieved with addition of a minimum of 13 % (by weight) chromium, and up to 26 % is used for harsh environments. Stainless Steel 317 Wing Nuts is also used as an automotive and aerospace structural alloy and construction material in large buildings.<\/span><\/p>\n\n\n\n\nSS 317 Bolt\/Nut Specifications<\/strong><\/span><\/h3>\n<\/td>\n<\/tr>\n\nSpecifications<\/strong><\/span><\/td>\n:<\/strong><\/span><\/td>\nASTM A 193 ASME SA 193<\/span><\/td>\n<\/tr>\n\nStandard<\/strong><\/span><\/td>\n:<\/strong><\/span><\/td>\nDIN, ASTM, BS and all International Standards<\/span><\/td>\n<\/tr>\n\nLength<\/strong><\/span><\/td>\n:<\/strong><\/span><\/td>\n3 mm to 200 mm<\/span><\/td>\n<\/tr>\n\nSize<\/strong><\/span><\/td>\n:<\/strong><\/span><\/td>\nM3 \u2013 M56 | 3\/6\u2033 to 2\u2033 | Custom Sizes<\/span><\/td>\n<\/tr>\n\nType<\/strong><\/span><\/td>\n:<\/strong><\/span><\/td>\nHex Head Bolts, Square Bolts, U bolts, Eye bolts, T bolt, Hex Bolt, Lag Bolts, Counter sunk Bolts, Hex Head nuts, Square nuts, Lock nuts, Eye nuts, wing nuts, T nuts, Panel Nuts, Coupling Nuts, Dome nuts, Acorn Nuts.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n317 Stainless Steel Bolt\/Nut Chemical Composition<\/strong><\/span><\/h3>\n\n \n\n\nGrade<\/strong><\/span><\/td>\nC<\/strong><\/span><\/td>\nMn<\/strong><\/span><\/td>\nSi<\/strong><\/span><\/td>\nP<\/strong><\/span><\/td>\nS<\/strong><\/span><\/td>\nCr<\/strong><\/span><\/td>\nMo<\/strong><\/span><\/td>\nNi<\/strong><\/span><\/td>\nN<\/strong><\/span><\/td>\n<\/tr>\n\n317<\/strong><\/span><\/td>\nmin.<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | 18.0<\/span><\/td>\n | \u2013<\/span><\/td>\n | 11.0<\/span><\/td>\n | \u2013<\/span><\/td>\n<\/tr>\n\nmax.<\/span><\/td>\n | 0.8<\/span><\/td>\n | 2.0<\/span><\/td>\n | 1.00<\/span><\/td>\n | 0.040<\/span><\/td>\n | 0.03<\/span><\/td>\n | 20.0<\/span><\/td>\n | 14.0<\/span><\/td>\n | \u2013<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nStainless Steel 317 Bolt\/Nut Mechanical Properties<\/strong><\/span><\/h3>\n\n \n\n\nGrade<\/strong><\/span><\/td>\nTensile Strength (MPa) min<\/strong><\/span><\/td>\nYield Strength 0.2% Proof (MPa) min<\/strong><\/span><\/td>\nElongation (% in 50mm) min<\/strong><\/span><\/td>\nHardness<\/strong><\/span><\/td>\n<\/tr>\n\nRockwell B (HR B) max<\/strong><\/span><\/td>\nBrinell (HB) max<\/strong><\/span><\/td>\n<\/tr>\n\n317<\/span><\/td>\n | 515<\/span><\/td>\n | 205<\/span><\/td>\n | 35<\/span><\/td>\n | 95<\/span><\/td>\n | 217<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nStainless Steel 317 Bolt\/Nut Physical Properties<\/strong><\/span><\/h3>\n\n \n\n\nGrade<\/strong><\/span><\/td>\nDensity (kg\/m3)<\/strong><\/span><\/td>\nElastic Modulus (GPa)<\/strong><\/span><\/td>\nMean Coefficient of Thermal Expansion (m\/m\/0C)<\/strong><\/span><\/td>\nThermal Conductivity (W\/m.K)<\/strong><\/span><\/td>\nSpecific Heat 0-1000C (J\/kg.K)<\/strong><\/span><\/td>\nElectrical Resistivity (n.m)<\/strong><\/span><\/td>\n<\/tr>\n\n0-1000C<\/strong><\/span><\/td>\n0-3150C<\/strong><\/span><\/td>\n0-5380C<\/strong><\/span><\/td>\nat 1000C<\/strong><\/span><\/td>\nat 5000C<\/strong><\/span><\/td>\n<\/tr>\n\n317<\/strong><\/span><\/td>\n8000<\/span><\/td>\n | 193<\/span><\/td>\n | 17.2<\/span><\/td>\n | 17.8<\/span><\/td>\n | 18.4<\/span><\/td>\n | 16.2<\/span><\/td>\n | 21.5<\/span><\/td>\n | 500<\/span><\/td>\n | 720<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nEquivalent Grades for 317 Stainless Steel Bolt\/Nut<\/strong><\/span><\/h3>\n\n \n\n\nGrade<\/strong><\/span><\/td>\nUNS No<\/strong><\/span><\/td>\nOld British<\/strong><\/span><\/td>\nEuronorm<\/strong><\/span><\/td>\nSwedish SS<\/strong><\/span><\/td>\nJapanese JIS<\/strong><\/span><\/td>\n<\/tr>\n\nBS<\/strong><\/span><\/td>\nEn<\/strong><\/span><\/td>\nNo<\/strong><\/span><\/td>\nName<\/strong><\/span><\/td>\n<\/tr>\n\n317<\/span><\/td>\n | S31700<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | 1.4449<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nSS 317 Bolt\/Nut Application Industries<\/strong><\/span><\/h3>\n\n- Off-Shore Oil Drilling Companies<\/span><\/li>\n
