About Carbon steel
Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Carbon steel
1) Carbon steel can be divided into three types: carbon structural steel, carbon tool steel and free-cutting structural steel according to the purpose. Carbon structural steel is further divided into engineering construction steel and machine-made structural steel;
(2) According to the smelting method, it can be divided into open hearth steel and converter steel;
(3) According to the deoxidation method, it can be divided into boiling steel (F), killed steel (Z), semi-killed steel (b) and special killed steel (TZ);
(4) 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%);
(5) According to the quality of steel, carbon steel can be divided into ordinary carbon steel (containing phosphorus and sulfur), high-quality carbon steel (containing phosphorus and sulfur) and high-quality steel (containing phosphorus and sulfur) ) And premium quality steel.
