Chrome rod made of SAE1045 S45C C45E 20MnV6 and 38MnVS6 steel

Chrome rod made of SAE1045, S45C, C45E, 20MnV6 and 38MnVS6 steel is designed for high-performance applications requiring precision and durability. As leading hard chrome plated rod suppliers, we provide chrome rods with external diameter accuracy of f7 f8 and a maximum surface roughness of Ra0.2μm, ensuring superior performance. The hard chrome thickness is a minimum of 15μm for diameters below Φ22.225mm and 20μm for diameters of Φ24mm and above. With a minimum surface hardness of HV850, our chrome rods offer excellent wear resistance. Straightness is maintained at a maximum of 0.25/1000mm for diameters under Φ20mm and 0.2/1000mm for larger sizes. Roundness tolerance is controlled at half the specification, ensuring a precise fit. Available in standard lengths from 3M to 6M and sizes from Φ6 to Φ255mm (Φ1/4” to Φ10”), these rods are tested for corrosion resistance under ISO 9227 NSS standards, achieving R9 ratings at 72hr for Φ<20mm and 120hr for Φ≥20mm. NSS and CASS testing is conducted in our in-house laboratory for guaranteed quality.


Durable Chrome Rod and Hard Chrome Plated Bar for Hydraulic Applications

Our chrome rod and hard chrome plated bar are designed for high-performance hydraulic and pneumatic cylinders, delivering exceptional durability, strength, and corrosion resistance. These components play a vital role in ensuring smooth operation, long service life, and reduced maintenance costs, making them ideal for demanding industrial applications.

  • Superior Corrosion Resistance for Harsh Environments
    Hydraulic cylinders are frequently exposed to moisture, high temperatures, and corrosive chemicals, especially in marine, chemical, and heavy industrial settings. To combat these challenges, our chrome rods and hard chrome plated bars meet ISO 9227 NSS corrosion resistance standards, providing superior protection against rust and oxidation. This ensures long-term performance even in the most harsh and corrosive environments.
  • Precision Engineering and Quality Assurance
    Each chrome rod undergoes rigorous testing in our in-house salt spray laboratory and at the Taiwan Metal Industries Research & Development Centre to guarantee top-tier quality. Our corrosion resistance testing meets ISO standards, achieving a rating of R10 with a testing period of up to 1000 hours, ensuring exceptional surface protection and wear resistance.
  • Reliable Performance for Hydraulic and Pneumatic Cylinders
    Our hard chrome plated bars feature an advanced surface treatment process that enhances hardness and durability, making them highly resistant to wear, impact, and mechanical stress. This ensures smooth piston movement, reduced friction, and improved sealing efficiency, which are essential for high-pressure hydraulic systems.

Key Applications of Chrome Rods and Hard Chrome Plated Bars

✔ Hydraulic and pneumatic cylinders requiring high wear resistance
✔ Industrial automation and machinery for precise motion control
✔ Marine and offshore equipment exposed to saltwater and humidity
✔ Heavy-duty construction and mining equipment operating in extreme conditions

By choosing our chrome rod and hard chrome plated bar, you ensure maximum efficiency, extended lifespan, and superior corrosion resistance for your hydraulic and pneumatic systems. Our commitment to precision manufacturing and strict quality control guarantees high-performance components that withstand harsh environments and demanding industrial applications.
