It is a kind of carbon content of less than 2.11 percent, and not specifically doped with metal elements of steel, can also be called carbon steel or carbon steel. In addition to carbon, it has a small amount of silicon, manganese, sulfur, phosphorus and other elements, the higher the carbon content, the better the hardness, the better the strength, but the plasticity will be worse.

The advantages of carbon steel plate are:

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

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

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

The disadvantages of carbon steel plate are:

1, His thermal hardness is not good, when used as a tool material, the temperature exceeds 200 degrees, the hardness and wear resistance will become worse.

2, His hardenability is not good, the diameter of water quenching is usually maintained at 15 to 18 mm, and the diameter and thickness of the unquenched is usually 6 mm, so it is easy to deformation or cracking problems.

What is the classification of carbon steel

1, According to the use can be divided into structure, tools, free cutting structural steel these three categories.

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

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

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