What is carbon steel? Is it strong

Carbon steel is a very strong material, its strength and hardness are very high. Carbon steel refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally do not add a large amount of alloying elements, sometimes known as carbon steel or carbon steel. Carbon steel, also known as carbon steel, refers to iron-carbon alloys with carbon content of less than 2% WC. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, phosphorus and other elements.

According to different uses, carbon steel can be divided into carbon structural steel, carbon tool steel and free cutting structural steel three categories. Among them, carbon structural steel is divided into building structural steel and machine manufacturing structural steel two kinds; According to the smelting method can be divided into open hearth steel, converter steel and electric furnace steel; According to the deoxidation method can be divided into boiling steel (F), killed steel (Z), semi-killed steel (b) and special killed steel (TZ); According to 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 (higher phosphorus and sulfur content), high-quality carbon steel (lower phosphorus and sulfur content) and high-grade high-quality steel (lower phosphorus and sulfur content) and extra high quality steel.

In general, in carbon steel, the higher the carbon content, the greater the hardness, the higher the strength, but the lower the plasticity. Therefore, when using carbon steel, it is necessary to choose the appropriate type and specification according to the specific situation.
