SAE J403 Carbon Steel Bars are widely used carbon steel products designed to meet the chemical composition requirements defined by the SAE system for carbon steels. These steels are commonly used for manufacturing mechanical and structural components where reliable strength, machinability, and heat treatment response are required. Manufactured in accordance with SAE J403, this specification establishes the chemical composition limits for a wide range of carbon steels used in semifinished products, hot-rolled bars, cold-finished bars, wire rods, plates, sheets, strip, welded tubing, and seamless tubing. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of SAE J403 Carbon Steel Bars, supplied with mill test certificates and strict quality inspection as per international standards. Forms of Supply (as per specification): Hot rolled round bars, Black bars, Bright bars, Cold drawn bars, Peeled bars, Turned bars, Ground bars, Forged round bars Available Grades (as per SAE J403): 1005, 1006, 1008, 1010, 1012, 1015, 1016, 1017, 1018, 1019, 1020, 1021, 1022, 1025, 1026, 1030, 1035, 1040, 1045, 1050, 1055, 1060, 1070, 1075, 1080, 1085, 1090, 1095, 1110, 1117, 1118, 1119, 1120, 1126, 1137, 1141, 1144, 1146, 1151, 1155, 1157, 1159, 1211, 1212, 1213, 1215, 1218, 1221 Explanation of SAE Designation: • The first two digits indicate the steel type (10xx – plain carbon steel) • The last two digits indicate the approximate carbon content in hundredths of a percent Typical Chemical Composition (varies by grade): • Carbon (C): 0.05% – 1.00% depending on grade • Manganese (Mn): Controlled to improve strength and hardenability • Silicon (Si): Present in small amounts for deoxidation • Phosphorus (P): Restricted to specified maximum limits • Sulphur (S): Controlled depending on machinability requirements Mechanical Properties (Typical – Grade Dependent): • Tensile Strength: Varies with carbon content • Yield Strength: Grade dependent • Elongation: Controlled for ductility • Hardness: Increases with carbon content and heat treatment Key Features: • Wide range of carbon steel grades • Good machinability and formability • Suitable for heat treatment • Consistent chemical composition • Reliable mechanical performance Material Characteristics: SAE J403 carbon steel bars provide a broad selection of low, medium, and high carbon steels suitable for various industrial applications.
