20MnChemical Composition

20Mn is a low-alloy high-strength structural steel, which is widely used in industrial production and construction. It has a series of excellent characteristics, including high strength, excellent fatigue resistance, good corrosion resistance, good weldability and machinability.

The following is the chemical composition specification of 20Mn:

Carbon (C) : 0.17-0.24%

Silicon (Si) : 0.17-0.37%

Manganese (Mn) : 1.40-1.80%

Phosphorus (P) : ≤0.035%

Sulfur (S) : ≤0.035%

Due to the low alloy properties of 20Mn, it has good machinability and weldability, and can be used to manufacture various steel parts and machine parts, such as bearings, gears, couplings, jacks, auto parts and so on. In addition, the material can also be used to manufacture some steel plates and pipes with higher strength requirements.

In general, 20Mn has a variety of excellent characteristics, these characteristics are the reason why it is widely used. In various fields, by selecting the appropriate processing methods and process parameters, the best performance and quality can be obtained, thereby improving the service life and reliability of the product
