(1) According to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and free cutting structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two;

(2) According to the smelting method can be divided into open-hearth steel, converter steel;

(3) According to the deoxidation method can be divided into boiling steel (F), killed steel (Z), semi-killed steel (b) and special killed steel (TZ);

(4) According to 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 (higher phosphorus and sulfur content), high-quality carbon steel (lower phosphorus and sulfur content) and high-grade high-quality steel (lower phosphorus and sulfur content) and extra high quality steel.

Generally, the higher the carbon content of carbon steel, the greater the hardness, the higher the strength, but the lower the plasticity.

We strictly implement the product factory inspection system. For the delivered steel products, the company provides quality certificates to ensure their quality.

In order for the products to arrive safely, we choose sturdy sea-resistant packaging or according to your needs. Professional and sturdy packaging to protect plates, coils, profiles, bars, pipes, wire rods etc. to the greatest extent and avoid bumps and scratches during transportation.
