Product Description

Advantages of 40Cr Chrome Plated Rod Normalized (HRC 15–22)

The 40Cr Chrome Plated Rod Normalized (HRC 15–22) offers several advantages that make it stand out in the market:


High Strength and Hardness

Normalized to HRC 15–22, ensuring both strength and controlled toughness.


Superior Wear Resistance

Hard chrome plating provides a smooth surface with long service life.


Corrosion Protection

The chrome layer resists rust and oxidation, suitable for outdoor or humid environments.


Excellent Straightness

Precision straightening ensures minimum deflection, ideal for hydraulic cylinders.


Dimensional Accuracy

Tightly controlled tolerances allow easy assembly and compatibility with seals.


Stable Performance

Normalized structure improves fatigue resistance under dynamic loads.

For distributors and stockists, these advantages mean fewer customer complaints, longer equipment lifespan, and a stronger competitive edge in the hydraulic components market.



Production Process of 40Cr Chrome Plated Rod Normalized (HRC 15–22)

The manufacturing of 40Cr Chrome Plated Rod Normalized (HRC 15–22) follows a strict process to ensure consistent quality:

  1. Raw Material Selection

    Premium 40Cr steel is sourced to guarantee mechanical strength.

  2. Cutting and Rough Machining

    Bars are cut to length and prepared for processing.

  3. Heat Treatment (Normalization)

    Rods are normalized to achieve hardness HRC 15–22, improving toughness and machinability.

  4. Peeling or Grinding

    Surface machining removes defects and prepares for chrome plating.

  5. Polishing

    Precision polishing creates a smooth base surface.

  6. Hard Chrome Plating 

    A uniform chrome layer (20–30 microns) is applied for wear and corrosion resistance.

  7. Final Grinding & Polishing

    Achieves mirror finish with Ra ≤ 0.2 μm.

  8. Straightening & Quality Check

    Ensures straightness ≤ 0.2mm/m and dimensional accuracy.

  9. Packing & Shipping

    Protected with oil film, paper, or plastic to prevent damage during transport.

This controlled process guarantees consistency, making it easier for distributors and contractors to maintain inventory quality.
