Stainless Steel 347H Nuts And Bolts<\/strong>, which are achieved by adding other alloying elements, such as manganese, nickel, chrome, titanium and molybdenum to the basic mix. Stainless Steel 347H Hex Head Bolts contain a mass fraction of at least 10.5 % chromium and a maximum of 1.2 % carbon. Other important alloying elements of Stainless Steel 347H Hex Head Nuts include Ni, Mo, Cu and many others, depending on the desired properties and application.<\/span><\/p>\n<\/span><\/p>\nUsually steels that do not form rust in the natural environment are named as Stainless Steel 347H Square Bolts. The most important group within Stainless Steel 347H Square Nuts are the austenitic stainless steels, which contain a minimum of 18 % chromium and 8 % nickel. Austenitic Stainless Steel 347H Eye Bolts are not magnetizable, where the most important element besides iron is carbon.<\/span><\/p>\nDue to the austenitic structure, Stainless Steel 347H Eye Nuts show a good ductility, and at low temperatures are very cold formable and show good weldability. The properties of Stainless Steel 347H U-Bolts can be widely influenced by alloying elements and heat treatment conditions. The carbon is essential in Stainless Steel 347H Lock Nuts which are to be hardened by quenching and tempering. The hardness of Stainless Steel 347H T-Bolts, as with all steel groups, is directly related to the amount of carbon alloyed.<\/span><\/p>\n\n\n\n\nSS 347H 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>\n347H 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\n347H<\/strong><\/span><\/td>\nmin.<\/span><\/td>\n | 0.04<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | 17.0<\/span><\/td>\n | 3.00<\/span><\/td>\n | 9.0<\/span><\/td>\n | \u2013<\/span><\/td>\n<\/tr>\n\nmax.<\/span><\/td>\n | 0.10<\/span><\/td>\n | 2.0<\/span><\/td>\n | 1.00<\/span><\/td>\n | 0.045<\/span><\/td>\n | 0.030<\/span><\/td>\n | 19.0<\/span><\/td>\n | 4.00<\/span><\/td>\n | 13.0<\/span><\/td>\n | \u2013<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nStainless Steel 347H 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\n347H<\/span><\/td>\n | 515<\/span><\/td>\n | 205<\/span><\/td>\n | 40<\/span><\/td>\n | 92<\/span><\/td>\n | 201<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nStainless Steel 347H 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\n347H<\/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 347H 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\n347H<\/span><\/td>\n | S34709<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | 1.4961<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nSS 347H Bolt\/Nut Application Industries<\/strong><\/span><\/h3>\n\n- Off-Shore Oil Drilling Companies<\/span><\/li>\n
