Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel sheet a36 steel, and generally does not add a lot of alloy elements, sometimes it is also called ordinary carbon steel. Carbon steel refers to iron carbon alloy with carbon content of WC less than 2%. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus. According to the content of phosphorus and sulfur, the carbon steel can be divided into ordinary carbon steel, high quality carbon steel sheet a36 steel, high quality steel and super quality steel.
It is understood that X70 grade steel pipes are commonly used in foreign developed countries. Although the production and use of higher-strength X80 pipeline steel has a history of more than 20 years, the laying length in the world is less than 2,000 kilometers.
According to its surface quality, pickling steel sheet a36 sheet steel can be divided into I and N two groups; According to its cup protrusion depth can be divided into ordinary and deep two levels. Application: Mainly used in such as body clock case, flashlight case, instrument case, lamp mouth, automobile brake drum, etc. Steel plate size: thickness of 0.25-2mm.
