Description of carbon steel
Carbon steel is an iron carbon alloy with carbon content ranging from 0.0218% to 2.11%. Also called carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. The higher the carbon content in the general carbon steel, the greater the hardness, the higher the strength, but the lower the plasticity.
(1) according to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and free cutting structural steel, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two kinds;
(2) according to smelting method, it can be divided into open hearth steel and converter steel;
(3) According to the deoxidation method can be divided into boiling steel (F), killed steel (Z), semi-killed steel (B) and special killed steel (TZ);
(4) according to carbon content can be divided into low carbon steel (WC 0.25% or less) to carbon steel, medium carbon steel (WC0.25%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 (containing phosphorus, sulfur is higher), high quality carbon steel (containing phosphorus, sulfur is lower) and high quality steel (containing phosphorus, sulfur is lower) and super high quality steel.
