Steel billet is a primary product obtained by casting steel from a steelmaking furnace, typically in the form of slabs (for plate production), blooms (for section and wire rod production), and billets (for pipe production). It is an important semi-finished product in the iron and steel industry and possesses good malleability and workability. Steel billet can be used as raw material for downstream processes. By undergoing processing techniques such as rolling, forging, and drawing, it can be made into various specifications and shapes of finished steel products like steel plates, steel pipes, steel bars, etc. In fields such as construction, machinery manufacturing, shipbuilding, and automobile manufacturing, steel billets are widely used to produce all kinds of parts and structural materials. Carbon steel, also known as carbon steel, has a carbon content of approximately 0. 02%-2%. Carbon steel is classified into high-carbon steel, medium-carbon steel, and low-carbon steel. The higher the carbon content, the greater the hardness, strength, and wear resistance of the steel after heat treatment, and the more brittle it becomes. The lower the carbon content, the softer and more ductile it is.
