BAIJIAN - Third party testing organization
Carbon steel is an iron carbon alloy with a carbon content ranging from 0.0218% to 2.11%. Also known as carbon steel. Generally、 it also contains small amounts of silicon、 manganese、 sulfur、 and phosphorus. Generally、 the higher the carbon content in carbon steel、 the greater the hardness and strength、 but the lower the plasticity (1) Carbon steel can be divided into three types according to its purpose: carbon structural steel、 carbon tool steel、 and free cutting structural steel. Carbon structural steel is further divided into two types: engineering construction steel and machine manufacturing structural steel (2) According to the smelting method、 it can be divided into open-hearth steel and converter steel (3) According to the deoxygenation method、 it 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 (WC 0.25-0.6%)、 and high carbon steel (WC> 0.6%) According to the quality of steel、 carbon steel can be divided into ordinary carbon steel (with higher phosphorus and sulfur content)、 high-quality carbon steel (with lower phosphorus and sulfur content)、 high-grade high-quality steel (with lower phosphorus and sulfur content)、 and special grade high-quality steel
