What is carbon steel?

Mainly refers to the carbon content of less than 2.11% without special alloying elements. Sometimes called plain carbon steel or carbon steel.
Carbon steel, also known as carbon steel, refers to iron carbon alloy with carbon Wc less than 2.11%.
Carbon steel in addition to carbon generally also contains a small amount of silicon, manganese, sulfur, phosphorus.
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 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 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.
Description: General carbon steel carbon content is higher hardness, strength is higher, but the plasticity is low.
