Carbon Steel Hot Rolled Coil

Carbon steel hot rolled coil is produced by continuously rolling steel billets at a temperature above the recrystallization point, resulting in high strength and good ductility. Hot rolled coils have a relatively rough surface but offer a wide thickness range, making them suitable for various industrial applications.
Carbon steel hot rolled coils are widely used in construction, machinery manufacturing, automotive parts, pipe production, and shipbuilding. They serve as the basic material for making steel sheets, profiles, pipes, and structural components.

Manufacturing Process

Application

Carbon hot-rolled steel plates are used in the construction sector and for welding such as cantilever cranes, construction equipment, railway tracks, agricultural equipment and heavy vehicle frames.By varying the content of carbon steel, different qualities of steel can be produced.In general, the higher the carbon content in steel, the more brittle, the harder, and the less tough the steel is.
