Carbon Steel

Carbon steel is an iron-carbon alloy with a carbon content ranging from 0.0218% to 2.11%. It is also called carbon steel. It typically also contains small amounts of silicon, manganese, sulfur, and phosphorus. Generally, the higher the carbon content in carbon steel, the harder and stronger it is, but the lower its plasticity.

Classification：

(1) According to the purpose, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel. Carbon structural steel is further 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 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 (high phosphorus and sulfur content), high-quality carbon steel (low phosphorus and sulfur content), high-grade high-quality steel (lower phosphorus and sulfur content) and special high-quality steel.
