Advantages Of Carbon Steel Plate

1. After heat treatment, the hardness and wear resistance can be improved.

2. The hardness is appropriate during annealing, and the machinability is good.

3. Its raw materials are very common, so it is easy to find, so the production cost is not high.

Carbon Steel Plate Classification

1. According to the application, it can be divided into three categories: structure, tool, and free-cutting structural steel.

2. According to the way of smelting, it can be divided into three types: open hearth steel, converter steel and electric furnace steel

3. According to the deoxidation method, it can be divided into boiling steel, killed steel, semi-killed steel and special killed steel.

4. According to the carbon content, it can be divided into three types: low carbon, medium carbon and high carbon.

Product Details

Steel can be divided into low carbon steel, medium carbon steel and high carbon steel. Low carbon steel – carbon content is generally less than 0.25%; medium carbon steel – carbon content is generally between 0.25 and 0.60%; high carbon steel – carbon content is generally greater than 0.60%.
