Carbon steel is an iron carbon alloy with a carbon content of 0.0218% ~ 2.11%. Also called carbon steel. Generally, it also contains a small amount of silicon, manganese, sulfur and phosphorus. Generally, the higher the carbon content in carbon steel, the higher the hardness, the higher the strength, but the lower the plasticity. According to the use, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free cutting structural steel, and carbon structural steel can be divided into engineering construction steel and machine manufacturing structural steel; (2) According to the smelting method, it can be divided into open hearth steel and converter steel; (3) According to the deoxidation method, it can be divided into boiling steel (f), killed steel (z), semi killed steel (b) and special killed steel (TZ); (4) According to carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25% - 0.6%) and high carbon steel (WC > 0.6%); (5) According to the quality of steel, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur), high-quality steel (lower phosphorus and sulfur) and super high-quality steel.
