Since 2006

Induction hardening ensures deep case hardness for wear resistance.
SS431 stainless steel provides protection against rust and pitting, even in marine environments.
Ensures durability in heavy-duty hydraulic and mechanical applications.
Smooth surface finish improves seal performance and reduces friction.
Resistant to abrasion, fatigue, and deformation under extreme conditions.
Suitable for hydraulic cylinders, offshore engineering, industrial automation, and precision machinery.
Manufactured under strict process control with full traceability.
Meets ISO, DIN, ASTM, and GB standards for performance and reliability.

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

The unique combination of corrosion resistance, hardness, and strength makes SS431 Chrome Plated Rod ideal for various industries:
Piston rods for industrial and mobile hydraulic systems.
Offshore equipment, oil rigs, and shipbuilding.
Excavators, loaders, cranes, and concrete pump trucks.
Linear guides, shafts, and precision machinery.
Components requiring high fatigue resistance and strength.
Wind turbines, hydroelectric systems, and oil & gas machinery.
