20MnV6 ID Not Honed Hollow Chrome Plated Rod

The 20MnV6 ID Not Honed Hollow Chrome Plated Rod is a precision-engineered hollow piston rod made from 20MnV6 steel, a material known for its excellent machinability, high tensile strength, and uniform microstructure. This product features a hollow interior to reduce overall weight while maintaining rigidity, making it ideal for long-stroke hydraulic cylinders and mechanical systems that require both strength and efficiency. The inner diameter (ID) is not honed, meaning it retains the original bore finish from the drilling process — suitable for non-sealing applications or when the internal surface finish is not critical.

Product Description

 

Chemical Composition of 20MnV6 Steel

Element Content (%)
Carbon (C) 0.17–0.23
Manganese (Mn) 1.30–1.70
Silicon (Si) 0.10–0.35
Vanadium (V) 0.07–0.12
Sulphur (S) ≤ 0.035
Phosphorus (P) ≤ 0.035

This composition provides 20MnV6 with a perfect balance between strength, impact resistance, and machinability, making it one of the most popular steels for hydraulic piston rods and mechanical shafts.

Manufacturing Process of 20MnV6 ID Not Honed Hollow Chrome Plated Rod

EASTAI follows a strict manufacturing process to ensure each 20MnV6 hollow chrome plated rod meets international standards for mechanical strength and surface quality.

  1. Material Selection — Certified 20MnV6 steel with uniform grain structure.
  2. Drilling / Boring — The hollow section is produced by deep-hole drilling or trepanning.
  3. Heat Treatment — Normalizing and tempering to enhance mechanical strength and toughness.
  4. Precision Turning & Grinding — Ensures consistent dimensions and outer surface accuracy.
  5. Hard Chrome Plating — Uniform chrome layer applied to resist corrosion and wear.
  6. Polishing — Achieves a mirror finish to enhance sealing and aesthetics.
  7. Final Inspection — Every rod is tested for hardness, roughness, straightness, and plating thickness.

All processes are carried out under ISO9001 quality management standards, ensuring high repeatability and product reliability.
