35MnBH/40Mn2 Steel Analysis and Application

In the construction machinery industry, the undercarriage parts of excavators and bulldozers are subjected to extreme working conditions and huge loads. As the core components of the undercarriage parts, the track chain and perakitan tautan trek have extremely high requirements for material properties. 35MnBH and 40Mn2 are two common alloy steels that are widely used in excavator chassis parts.

Material analysis of 35MnBH steel

35MnBH is a low alloy high strength steel, its main components include:

Its features include:

• Kekuatan tinggi dan ketahanan aus yang tinggi: Due to the addition of boron, 35MnBH has excellent hardenability, which significantly improves the hardness and wear resistance of the material.
• Good machinability: Despite its high hardness, 35MnBH still has good cutting and welding performance.
• Tahan benturan kuat: Suitable for use under high impact load conditions.

Material analysis of 40Mn2 steel

40Mn2 is another common medium carbon alloy steel, and its main components are:

Its characteristics include:

• High toughness and high strength: The high manganese content makes 40Mn2 have higher strength and toughness.
• Good hardenability: After quenching and tempering, 40Mn2 can obtain excellent comprehensive mechanical properties.
• Ketahanan korosi: Compared with ordinary carbon steel, 40Mn2 has better corrosion resistance.

The main difference between 35MnBH and 40Mn2

Hardness and toughness:

• Due to the presence of boron, 35MnBH has stronger hardness and wear resistance, which is suitable for high wear applications.
• 40Mn2 has higher toughness and can better withstand impact loads.

Ketahanan aus:

• 35MnBH is superior to 40Mn2 and is more suitable for parts that need to be in contact with hard ground for a long time.

Applicable environment:

• 35MnBH is suitable for high wear and high load environments, such as mining.
• 40Mn2 is more suitable for medium load applications that require a certain toughness, such as earthwork.

Application in track chain and track link assembly

Track chain:

• 35MnBH: Due to its high wear resistance and hardness, 35MnBH is very suitable as the main material of crawler chain, which can significantly increase the service life of the chain, especially in harsh environments.
• 40Mn2: Its high toughness makes it suitable for chain components that need to withstand high impact forces, which can reduce the risk of chain breakage.

Track assembly:

• 35MnBH: In the crawler assembly, key components such as track links and pins usually use 35MnBH to improve wear resistance.
• 40Mn2: Suitable for parts that require extra toughness, such as load-bearing sprockets or drive wheels.

Advantages of the two materials

Advantages of 35MnBH:

• High wear resistance is suitable for harsh working conditions and reduces replacement frequency.
• Excellent processing performance, suitable for a variety of manufacturing needs.

Advantages of 40Mn2:

• Higher toughness, can withstand greater impact loads.
• Good corrosion resistance, suitable for humid environments.

Suitable application environment

Applicable environment for 35MnBH:

• High wear and high impact scenes such as mines and quarries.
• Engineering projects in deserts or extreme temperature conditions.

Applicable environment for 40Mn2:

• Construction environment with medium load and high humidity.
• Application scenarios for earthwork or light machinery.
