Brief Introduction of Carbon Steel

Carbon steel is an iron-carbon alloy containing no other alloying elements, except for silicon, manganese, phosphorus, sulfur and other impurities, containing less than 2.11% of carbon and containing iron, carbon and limited amounts. The carbon content of industrial carbon steel is generally 0.05% to 1.35%. The performance of carbon steel depends mainly on the carbon content. As the carbon content increases, the strength and hardness of the steel increase, and the ductility, weldability and weldability decrease.

Compared with other steels, carbon steel is the earliest used, low cost, wide performance range and maximum dosage. Carbon steel is suitable for water, steam, air, hydrogen, ammonia, nitrogen and petroleum products with a nominal pressure of PN ≤ 32.0 MPa and a temperature of -30-425 °C. Commonly used grades are WC1, WCB, ZG25 and high quality steel 20, 25, 30 and low alloy structural steel 16Mn.
