SAE 1008 Free Cutting Steel
We are SAE 1008 Free Cutting Steel Manufacturers, Suppliers, and Exporters in Mumbai, India. STEEL MART is an ISO 9001:2015 certified company established in 1986, supplying premium carbon and free-cutting steel products worldwide. We specialize in manufacturing and supplying SAE 1008 Free Cutting / Low Carbon Steels (SAE 1008 / AISI 1008 / ASTM A510 Grade 1008 / DIN 1.0204) that meet international quality standards for precision turned components, cold-headed fasteners, electronic pinions, automotive sleeves, wire rods, and bright drawn bars. SAE 1008 is a low-carbon steel specified under American Standards (AISI / SAE) for applications requiring high ductility, superior surface finish, excellent cold formability, and reliable free-machining characteristics. Formulated with a low carbon content (max 0.10%), SAE 1008 offers exceptional weldability, soft ductile matrix, and clean response to high-speed automatic lathe turning, cold heading, and bending operations. In bright cold drawn condition (+C), SAE 1008 provides tight h9/h10 bar tolerances, smooth scale-free surface, and improved yield strength (280–380 MPa). It also responds exceptionally well to case hardening (carburizing) to achieve high surface wear resistance up to 58–62 HRC while maintaining a tough ductile core. SAE 1008 Free Cutting Steel is widely specified across automotive electrical connectors, rivets, tubular fittings, appliance shafts, and high-speed turned fasteners.
Our SAE 1008 Free Cutting Steels are 100% Prime – Tested & Guaranteed, with controlled chemistry and dimensional accuracy. Every shipment is backed by proper Mill Test Certificates (MTC) per EN 10204 3.1 certification. STEEL MART ensures strict quality inspection and prompt worldwide delivery.
What is SAE 1008 Free Cutting Steel?
SAE 1008 Free Cutting / Low Carbon Steel (AISI 1008 / SAE 1008 / ASTM A510 / DIN 1.0204) is a low-carbon engineering steel renowned for its soft ductile matrix, excellent cold forming capability, and clean turning characteristics. Containing a maximum carbon content of 0.10%, SAE 1008 provides high ductility, excellent weldability, and low hardness, making it ideal for automatic lathe machining followed by severe cold heading, bending, or swaging. In bright cold drawn condition (+C), SAE 1008 achieves uniform h9/h10 tolerances, smooth surface finish, and improved tensile strength (330–430 MPa). It responds well to case carburizing to establish a hard wear-resistant outer case (58–62 HRC) while preserving core toughness.
