Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel.
Generally also contains a small amount of silicon, manganese, sulfur, phosphorus.
Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.
According to the application, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel, and carbon structural steel is further divided into engineering construction steel and machine manufacturing structural steel;
According to The smelting method can be divided into open hearth steel and converter steel;
According to the deoxidation method, it can be divided into boiling steel (F), killed (Z), semi-killed steel (b) and special killed steel (TZ);
According to the content of Carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC>0.6%);
According to the quality of steel, it can be divided into Carbon steel is divided into ordinary carbon steel (with high phosphorus and sulfur), high-quality carbon steel (with low phosphorus and sulfur), high-grade high-quality steel (with low phosphorus and sulfur) and super high-quality steel.
