High manganese steel bushing can be customized

Excavator bushing

Important parts in the mechanical structure of the excavator.

It is mainly installed at the joints of the excavator's boom, dipper rod, bucket and other working devices, as well as the slewing mechanism and other parts.

Function:

It is to reduce the friction and wear of the joints, ensure that each component can rotate flexibly, and can buffer and support the force generated when the excavator is working, and ensure the stability and working accuracy of the equipment.

Main material: 

Cast steel Mn13 (high manganese steel)

The presence of a large amount of manganese causes the surface of the material to produce work hardening when it is impacted and pressed. This makes the surface hardness of the material increase sharply, thus having excellent wear resistance.

This material is often used in situations where it needs to withstand strong impact and wear, such as bucket teeth of excavators, hammer heads of crushers, cement machinery, and loaders.

Main ingredients: manganese, carbon

Features: high carbon content, high wear resistance, high hardness, impact resistance, and strong toughness

Manufacturing process:

• Ceramic process (custom bushing)

Rare metal content: can be changed and adjusted according to needs

Function: coating treatment, ceramic processing on the surface of the bushing enhances wear resistance and corrosion resistance, and extends the service life of the bushing.

Welding process: supports electric welding (manganese steel welding rod and stainless steel welding rod)

Water toughening treatment (directional cooling)

Quality inspection:

Hardness test: ensure that the surface hardness meets the wear resistance requirements;

Metallographic structure inspection: observe whether a single austenite structure is formed;

Non-destructive testing: such as ultrasonic testing to see if there are defects inside the bushing.
