Trusted chrome plated round bar suppliers with ISO 9227 NSS resistance

Trusted chrome plated round bar suppliers with ISO 9227 NSS resistance

As trusted chrome plated round bar suppliers, we provide high-quality round bars that meet rigorous industrial standards. Our chrome plated round bars are manufactured with precise external diameter accuracy of f7 and f8, ensuring superior performance in various applications. Each bar features a maximum surface roughness of Ra 0.2μm, delivering a smooth finish that reduces friction and enhances efficiency.

Our bars come with a hard chrome thickness of 15 μm for diameters less than Φ22.225mm and 20 μm for larger diameters (Φ24mm and above). The surface hardness is a minimum of HV 850, offering excellent wear resistance. We maintain strict tolerances for straightness, up to 0.25mm per 1000mm for diameters less than Φ20mm and 0.2mm per 1000mm for larger sizes. Roundness is controlled to a tolerance × 1/2 standard, ensuring precision in every bar.

Available in standard lengths from 3M to 6M and sizes ranging from Φ6 to Φ255 (Φ1/4” to Φ10”), our chrome plated round bars are designed for durability and reliability. We also offer customized lengths and specifications to meet specific requirements. Our products are tested for corrosion resistance according to ISO 9227 NSS standards, with resistance ratings of R9 /72hr NSS for diameters less than 20mm and R9 /120hr NSS for larger sizes. Both NSS and CASS tests can be performed in our own laboratory to ensure top quality.

Manufactured from premium steel grades such as JIS S45C, SAE1045, DIN CK45, EN C45E, ASTM 1045, and 20MnV6, our chrome plated round bars can be tailored to meet special specifications upon request. Choose our chrome plated round bars for unmatched quality, performance, and longevity.

Chrome Plated Rod: High-Quality Chrom Plated Round Bar

Discover our premium chrome plated rod, designed for exceptional performance and durability. As a leading supplier of chrome plated round bars, we ensure each rod meets stringent industry standards. Our chrome plated rods offer precise external diameter accuracy of f7 and f8, making them ideal for high-precision applications. The surface of each rod is finely finished with a maximum roughness of Ra 0.2μm, ensuring smooth operation and minimal friction.

The hard chrome plating on our rods varies by diameter, with a minimum thickness of 15 μm for rods less than Φ22.225mm and 20 μm for those Φ24mm and above. This robust coating provides a surface hardness of at least HV 850, offering excellent wear resistance and durability. We maintain rigorous tolerances for straightness, with a maximum deviation of 0.25mm per 1000mm for rods smaller than Φ20mm and 0.2mm per 1000mm for larger rods. Additionally, roundness is controlled to a tolerance × 1/2 standard, ensuring consistent performance and reliability.

Our standard chrome plated rods are available in lengths ranging from 3M to 6M and sizes from Φ6 to Φ255 (Φ1/4” to Φ10”). Custom lengths and specifications can be accommodated upon request. The rods also feature superior corrosion resistance, tested according to ISO 9227 NSS standards. Smaller diameters offer a resistance rating of R9 /72hr NSS, while larger diameters achieve R9 /120hr NSS, with NSS and CASS tests performed in our own laboratory for quality assurance.

Made from high-grade steel, including JIS S45C, SAE1045, DIN CK45, EN C45E, ASTM 1045, and 20MnV6, our chrome plated rods can be customized to meet special requirements. Choose our chrome plated rod for reliable, high-performance solutions tailored to your needs.
