Carbon Steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally does not add a large amount of alloying elements, and is sometimes called ordinary carbon steel or carbon steel.
Carbon steel is also called carbon steel, which refers to an iron-carbon alloy with a carbon content of less than 2% WC.
In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus.
1.According to the purpose, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel. Carbon structural steel is further divided into two types: building structural steel and machine-made structural steel;
2.According to the smelting method, it can be divided into open hearth steel, converter steel and electric furnace 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 the carbon content, 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%);
5.According to the phosphorus and sulfur content, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur) and high-quality high-quality steel (lower phosphorus and sulfur) and Premium quality steel.
Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.
