40Cr Honed Tube

Advantages of 40Cr Honed Tube

Choosing 40Cr Honed Tube brings multiple advantages compared to standard carbon steel honed tubes:

High Strength & Toughpness

40Cr alloy steel ensures excellent load-bearing capacity and resistance to impact.

Superior Wear Resistance

Suitable for high-frequency and heavy-duty hydraulic applications.

Precision Honed Surface

Smooth bore ensures low friction and efficient hydraulic sealing.

Extended Cylinder Life

Reduces wear on seals and pistons, increasing service life.

Heat Treatment Capability

40Cr can be quenched and tempered to improve hardness and durability.

Versatile Applications

Ideal for construction machinery, mining equipment, lifting platforms, and industrial hydraulics.

Production Process of 40Cr Honed Tube

To ensure superior quality and consistency, 40Cr Honed Tubes undergo a rigorous production process:

1. Raw Material Selection

   High-quality 40Cr alloy steel seamless pipes are sourced.

2. Cold Drawing / Hot Rolling

   Improves mechanical properties and refines tube dimensions.

3. Heat Treatment (Quenching & Tempering)

   Enhances hardness, strength, and fatigue resistance.

4. Boring

   Prepares inner bore for honing by removing irregularities.

5. Honing

   Precision honing achieves accurate dimensional tolerance and smooth surface finish.

6. Skiving & Roller Burnishing (Optional)

   Enhances surface roughness and bearing properties.

7. Straightening

   Ensures tube alignment and dimensional accuracy.

8. Inspection

   Dimensional, mechanical, and surface finish testing.

9. Packing & Storage

   Rust-proof packaging for safe storage and transport.
