Additionally, the reduced carbon content of this alloy, while limiting strength through thickness, provides better weldability than its 4140 steel counterpart. These properties make AISI 4130 steel bar a popular choice in the aerospace industry for manufacturing commercial and military aircraft components that require high strength and low weight.<\/p>\n<p style=\"font-weight: 400;\"><b><strong>Product Parameters<\/strong><\/b><\/p>\n<table style=\"font-weight: 400;\">\n<tbody>\n<tr>\n<td>Product Name<\/td>\n<td colspan=\"4\">AISI\/SAE 4130 Alloy Steel Bar<\/td>\n<\/tr>\n<tr>\n<td>Standard<\/td>\n<td colspan=\"4\">EN\/DIN\/JIS\/ASTM\/BS\/ASME\/AISI, etc.<\/td>\n<\/tr>\n<tr>\n<td>Common Round Bar Specifications<\/td>\n<td colspan=\"4\">3.0-50.8 mm,\u00a0Over 50.8-300mm<\/td>\n<\/tr>\n<tr>\n<td>Flat Steel\u00a0Common\u00a0Specifications<\/td>\n<td colspan=\"4\">6.35&#215;12.7mm, 6.35&#215;25.4mm, 12.7&#215;25.4mm<\/td>\n<\/tr>\n<tr>\n<td>Hexagon Bar\u00a0Common\u00a0Specifications<\/td>\n<td colspan=\"4\">AF5.8mm-17mm<\/td>\n<\/tr>\n<tr>\n<td>Square Bar\u00a0Common\u00a0Specifications<\/td>\n<td colspan=\"4\">AF2mm-14mm, AF6.35mm,\u00a09.5mm, 12.7mm, 15.98mm, 19.0mm, 25.4mm<\/td>\n<\/tr>\n<tr>\n<td>Length<\/td>\n<td colspan=\"4\">1-6meters,\u00a0Size Accept Custom<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"3\">Diameter(mm)<\/td>\n<td>Hot Rolling Round Bar<\/td>\n<td>25-600<\/td>\n<td>Cold Rolling\u00a0Square Bar<\/td>\n<td>6-50.8<\/td>\n<\/tr>\n<tr>\n<td>Hot Rolling\u00a0Square Bar<\/td>\n<td>21-54<\/td>\n<td>Cold Rolling\u00a0Hexagon Bar<\/td>\n<td>9.5-65<\/td>\n<\/tr>\n<tr>\n<td>Cold Rolling\u00a0Round bar<\/td>\n<td>6-101.6<\/td>\n<td>Forged Rebar<\/td>\n<td>200-1000<\/td>\n<\/tr>\n<tr>\n<td>Surface\u00a0Process<\/td>\n<td colspan=\"4\">Bright, Polished, Black<\/td>\n<\/tr>\n<tr>\n<td>Other Services<\/td>\n<td colspan=\"4\">Machining(cnc), Centerless Grinding(cg), Heat Treatment, Annealing, Pickling, Polishing, Rolling, Forging, Cutting, Bending, Small Machining, etc.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"font-weight: 400;\"><b><strong>Chemical Composition<\/strong><\/b><\/p>\n<table style=\"font-weight: 400;\">\n<tbody>\n<tr>\n<td>Grade<\/td>\n<td>Mn<\/td>\n<td>S<\/td>\n<td>C<\/td>\n<td>P<\/td>\n<td>Si<\/td>\n<td>Cr<\/td>\n<td>Mo<\/td>\n<\/tr>\n<tr>\n<td>AISI\u00a04130<\/td>\n<td>0.4-0.8<\/td>\n<td>0.04<\/td>\n<td>0.28-0.33<\/td>\n<td>0.035<\/td>\n<td>0.15-0.35<\/td>\n<td>0.8-1.1<\/td>\n<td>0.15-0.25<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"font-weight: 400;\"><b><strong>Mechanical Properties<\/strong><\/b><\/p>\n<table style=\"font-weight: 400;\">\n<tbody>\n<tr>\n<td>Grade<\/td>\n<td>Tensile Strength\u00a0N\/mm2\u00a0Min<\/td>\n<td>Yield Strength\u00a0N\/mm2\u00a0Min<\/td>\n<td>A, %\u00a0Min<\/td>\n<td>Z, %\u00a0Min<\/td>\n<\/tr>\n<tr>\n<td>AISI\u00a04130<\/td>\n<td>930<\/td>\n<td>735<\/td>\n<td>12<\/td>\n<td>50<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"font-weight: 400;\"><b><strong>Scope of Application<\/strong><\/b><\/p>\n<p style=\"font-weight: 400;\">SAE 4130 round bars are commonly used in structural applications, including brackets, gears, and some aircraft exteriors.<\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"e_text-36 s_title response-transition\">AISI 4130 carbon steel bar has excellent strength, toughness and processability.
