SAE 1010 Free Cutting Steel
We are SAE 1010 Free Cutting Steel Manufacturers, Suppliers, and Exporters in Mumbai, India. STEEL MART is an ISO 9001:2015 certified company established in 1986, supplying high-grade carbon and free-machining steel products to industries globally. We specialize in manufacturing and supplying SAE 1010 Free Cutting / Low Carbon Steels (SAE 1010 / AISI 1010 / ASTM A108 Grade 1010 / DIN 1.0301 / C10) that comply with national and international quality standards for precision turned parts, automotive fasteners, hydraulic fittings, electrical motor shafts, and automatic CNC lathe turned components. SAE 1010 is a plain low-carbon engineering steel specified under American Standards (AISI / SAE) for applications requiring balanced ductility, smooth surface finish, excellent weldability, and easy machinability. Formulated with 0.08–0.13% Carbon and 0.30–0.60% Manganese, SAE 1010 delivers a soft uniform ferrite-pearlite matrix ideal for fast chipping turning, cold heading, and bending. In bright cold drawn condition (+C), SAE 1010 achieves high dimensional accuracy (h9/h10 bar tolerances), clean scale-free surface, and elevated yield strength (300–400 MPa). It responds exceptionally well to case hardening (carburizing) to produce a glass-hard wear surface (58–62 HRC) over a tough shock-resistant core. SAE 1010 Free Cutting Steel is widely specified across automotive link pins, bushings, hydraulic tube fittings, electrical armatures, and turned industrial fasteners.
Our SAE 1010 Free Cutting Steels are 100% Prime – Tested & Guaranteed, with consistent chemical composition and dimensional straightness. Every consignment is supplied with proper Mill Test Certificates (MTC) per EN 10204 3.1 certification. STEEL MART guarantees strict quality inspection and prompt delivery.
What is SAE 1010 Free Cutting Steel?
SAE 1010 Free Cutting / Low Carbon Steel (AISI 1010 / SAE 1010 / ASTM A108 / DIN 1.0301 / C10) is a low-carbon engineering steel valued for its balanced combination of high ductility, good turning machinability, excellent weldability, and cold forming performance. Containing 0.08–0.13% Carbon and 0.30–0.60% Manganese, SAE 1010 machines smoothly on automatic lathes without excessive tool chatter. In bright cold drawn condition (+C), SAE 1010 provides enhanced yield strength (300–400 MPa), tight h9/h10 bar tolerances, and scale-free surface finish. It is ideal for components that require case hardening (carburizing) to obtain high surface wear resistance while retaining a tough core.
