CNC Machining Anti Rust Excavator Machine Parts Oil Surface Treatment Casting Services Product

In the demanding world of construction and mining equipment, excavator machine parts require exceptional durability and corrosion resistance to withstand harsh operating conditions. Our specialized manufacturing service integrates advanced CNC machining with professional anti-rust oil surface treatment technologies to deliver high-performance components that significantly extend service life while maintaining precise dimensional accuracy.

Material Selection and Mechanical Properties

We utilize premium materials specifically chosen for excavator applications, including high-strength alloy steels such as 4140 and 4340, along with ductile iron grades 65-45-12 and 80-55-06. These materials undergo rigorous quality verification to ensure consistent mechanical properties:

• Tensile strength: 620-895 MPa for alloy steels

• Yield strength: 415-745 MPa depending on heat treatment

• Impact toughness: 27-54 J at room temperature

• Hardness range: 24-32 HRC for optimal wear resistance
  The material selection process focuses on achieving the perfect balance between strength, toughness, and machinability for specific excavator applications.
