Common materials for excavator bucket shafts
The common materials and characteristics of excavator bucket shafts are as follows, integrating high wear resistance, impact resistance and processing technology requirements:
High-quality carbon structural steel (such as 45# steel)
High-frequency heat treatment with a depth of 8-10mm enhances surface hardness and wear resistance while maintaining core toughness .
Low cost, widely used in the manufacture of bucket shafts for small and medium-sized excavators .
Alloy steel (such as 40Cr, 20CrMnTi)
40Cr alloy steel forms a martensitic wear-resistant layer through high-frequency quenching, but it is prone to peeling off under impact.
The surface hardness of 20CrMnTi is high after carburizing and quenching, but it is brittle and needs to be used in combination with lubrication .
Isothermal quenched ductile iron (ADI)
High strength and wear resistance are achieved through isothermal treatment of austenite, and the service life is several times longer than that of traditional steel .
Suitable for high-load working conditions, such as excavator pins and bushings .
High manganese alloy steel (such as ZGMn13Cr2)
Containing 11%-14% manganese and 1.5%-2.5% chromium, the surface hardens after impact and has excellent wear resistance .
It is commonly used for bucket teeth, but is less applied to bucket shafts (selection should be based on specific working conditions) .
Note : Material selection should balance cost, working conditions (such as impact frequency, abrasive type) and maintenance conditions .
