|---|---|---|---|
Cold-rolled 1018 carbon steel coils are low-carbon steel products known for their exceptional surface smoothness, dimensional consistency, and enhanced mechanical properties. The cold-rolling process compresses the steel at room temperature, resulting in improved hardness, yield strength, and surface uniformity while retaining excellent formability and weldability. These coils are widely used in precision applications such as automotive brackets, hydraulic components, and consumer electronics housings. The material’s low carbon content (0.15–0.20%) ensures ease of machining and welding, while manganese (0.60–0.90%) contributes to wear resistance. Cold-rolled 1018 steel coils are often specified for projects requiring tight tolerances (±0.001″) and minimal surface imperfections. | |||
