What kind of material is carbon steel? What are the classifications?

The so-called carbon steel actually means that the mechanical properties depend on the carbon content in the steel. Generally, the steel without master alloy element is also called ordinary carbon steel or carbon steel, while the carbon steel is also called carbon steel, which means the iron carbon alloy with carbon content of less than 2% WC, and the carbon steel contains a small amount of silicon, manganese, sulfur and phosphorus besides carbon. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.

What are the classifications of carbon steel?
1. According to the application, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and easy to cut structural steel.
2. According to the smelting method, the carbon steel can be divided into open hearth steel, converter steel and electric furnace steel.
3. According to the deoxidation method, the carbon steel can be divided into boiling steel, killed steel, semi killed steel and special killed steel, which are represented by codes F, Z, B and TZ respectively.
4. According to the carbon content, carbon steel can be divided into three categories: low carbon steel, medium carbon steel and high carbon steel.
5. According to the content of sulfur and phosphorus, the carbon steel can be divided into ordinary carbon steel with higher content, high-quality carbon steel with lower content of phosphorus and sulfur, and high-quality steel with lower content of phosphorus and sulfur. Finally, there are four categories of super quality steel.
