What are the classifications of carbon steel plates?

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;

(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.
