(1) According to the use, carbon steel can be divided into three categories

What are the classifications of carbon steel plates?
(1) According to the use, 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 two types: 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 can be divided into ordinary carbon steel (higher phosphorus and sulfur content), high-quality carbon steel (lower phosphorus and sulfur content), high-grade high-quality steel (lower phosphorus and sulfur content) and special grade high-quality steel. steel. ​

Note: Generally, the higher the carbon content in carbon steel, the greater the hardness and strength, but the plasticity is lower.
