Advantages of SS430 Chrome Plated Rod (Induction Hardened)

• High hardness (HRC 50–62) for improved wear resistance
• Corrosion resistance from SS430 base material
• Precision chrome plating for smooth surface finish and reduced friction
• Enhanced fatigue resistance due to induction hardening
• Low maintenance and extended replacement intervals
• Wide compatibility with hydraulic cylinders, piston rods and industrial linear shafts

Production Process

• Raw material selection: high-quality SS430 for mechanical stability
• Cutting & straightening: bars cut to length and straightened to minimize deformation
• Peeling & grinding: surface machined for dimensional accuracy
• Induction hardening: surface heated by high-frequency induction and hardened to HRC 50–62
• Chrome plating: uniform chrome coating applied for wear and corrosion resistance
• Polishing & finishing: final surface treatment for low roughness
• Straightness & tolerance control: dimensional checks to ensure specified tolerances
• Packaging: rust-proof wrapping and custom packaging for safe transport

Applications

• Hydraulic cylinders (piston rods for heavy-duty hydraulic systems)
• Pneumatic cylinders requiring smooth linear motion
• Construction machinery (excavators, loaders, cranes)
