The manufacturing of SS431 Chrome Plated Rod involves advanced production technology to ensure precision, durability, and performance:
Raw Material Selection
High-quality SS431 stainless steel billets are sourced and tested for purity.
Peeling & Straightening
Removal of surface defects and improvement of dimensional accuracy.
Induction Hardening
Surface hardening process increases hardness to HRC 50–62 for wear resistance.
Tempering
Relieves internal stress, ensuring stability and toughness.
Centerless Grinding
Produces an accurate diameter with tight tolerance.
Polishing
Achieves a smooth surface for chrome plating adhesion.
Hard Chrome Plating
Adds a protective chromium layer with strong anti-rust performance.
Final Grinding & Finishing
Ensures surface roughness Ra ≤ 0.2µm and precise dimensional accuracy.
Inspection & Testing
100% tested for hardness, straightness, and coating thickness.
Packing & Delivery
Protected with oil film and anti-rust paper for global shipping.
