Carbon steel classification
(1) According to the purpose, carbon steel can be divided into carbon structural steel, carbon tool steel and free cutting structural steel. Carbon structural steel can be divided into 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 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%) and medium carbon steel (WCO. 25% - 0.6%)
And high carbon steel (WC > o.6%)
(5) According to the quality of steel, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur), high-grade high-quality steel (lower phosphorus and sulfur) and special grade high-quality steel
