Carbon steel

It mainly refers to the mechanical properties of steel depends on the carbon content of steel, and generally do not add a large number of alloalloy elements of steel, sometimes called general carbon steel or carbon steel.

Carbon steel, also known as carbon steel, refers to the iron carbon alloy with carbon content WC less than 2%.In addition to carbon steel generally contains a small amount of silicon, manganese, sulfur, phosphorus.

According to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and free cutting structural steel three categories, carbon structural steel is divided into building structural steel and machine manufacturing structural steel two;

According to the smelting method can be divided into open hearth steel, converter steel and electric furnace steel;

According to the deoxidation method, it can be divided into boiling steel (F), sedation steel (Z), semi-sedation steel (b) and special sedation steel (TZ);

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%);

According to the content of phosphorus and sulfur, carbon steel can be divided into ordinary carbon steel (containing phosphorus and sulfur higher), high-quality carbon steel (containing phosphorus and sulfur lower) and advanced high-quality steel (containing phosphorus and sulfur lower) and special high-quality steel.

Generally, the higher the carbon content in carbon steel, the greater the hardness, the higher the strength, but the lower the plasticity.
