SS431 Chrome Plated Rod Induction And Hardened (HRC 50-62)

The SS431 Chrome Plated Rod Induction and Hardened (HRC 50-62) is a premium shaft material designed for demanding hydraulic and mechanical applications. Made from SS431 stainless steel, it combines high tensile strength, excellent toughness, superior corrosion resistance, and outstanding wear performance. The rod undergoes precision chrome plating for enhanced surface hardness and induction hardening treatment (HRC 50–62) for improved fatigue life. It is widely used by distributors, stockists, and engineering contractors in hydraulic cylinders, linear motion systems, construction machinery, and marine equipment.

Production Process of SS431 Chrome Plated Rod

The manufacturing of SS431 Chrome Plated Rod involves advanced production technology to ensure precision, durability, and performance:

  1. Raw Material Selection

    High-quality SS431 stainless steel billets are sourced and tested for purity.

  2. Peeling & Straightening

    Removal of surface defects and improvement of dimensional accuracy.

  3. Induction Hardening

    Surface hardening process increases hardness to HRC 50–62 for wear resistance.

  4. Tempering

    Relieves internal stress, ensuring stability and toughness.

  5. Centerless Grinding

    Produces an accurate diameter with tight tolerance.

  6. Polishing

    Achieves a smooth surface for chrome plating adhesion.

  7. Hard Chrome Plating

    Adds a protective chromium layer with strong anti-rust performance.

  8. Final Grinding & Finishing

    Ensures surface roughness Ra ≤ 0.2µm and precise dimensional accuracy.

  9. Inspection & Testing

    100% tested for hardness, straightness, and coating thickness.

  10. Packing & Delivery

    Protected with oil film and anti-rust paper for global shipping.
