Hardened Surface 20MnV6 Chrome Piston Rod Custom Diameter
Hardened Surface 20MnV6 Chrome Piston Rod Custom Diameter is suitable for universal use and is very tough and corrosion-resistant. Hard chrome plating means that an especially thick chrome layer is applied between pre-honing and finishing the honing process. The layer thickness depends on the rod diameter and has a hardness of more than 800 HV. Hard chrome plated piston rods can be used between -15°C and 200°C.
Our Range of Product is made up from Prominent Quality. Our Product is also globally appreciated for their aesthetic finish. It designed to meet your specific needs for piston rod material in Hydraulic and Pneumatic Cylinders and other applications.
Size range: Diameter metric size min. 6 mm to 450mm and imperial size 1/4″ to 16″
External Diameter Tolerance: Our chrome plated bars are supplied with tolerance f7, f8, f9 on customers request.
Surface roughness: Ra0.2μm ~ Ra0.4μm (8 Ra – 16 Ra)
Chrome Layer thickness for ∅≤19.05 [mm] is minimum 15[µm] and for ∅>20[mm] is minimum 20[µm]
Corrosion Resistance is given by the salt spray tests results. These tests are following the ISO 9227 and ISO 10289 standards. The results of these tests are giving the rating of our products.
Straightness for ∅<20 [mm] is max 0,3 [mm]/1000 [mm] and for ∅≥20[mm] is max 0,2[mm]/1000[mm].
Surface Hardness – Chrome Layer hardness is minimum 850HV
The high performance of strength: The yield strength of chrome plated bars can be 75000 psi up to 100000 psi.
The chrome plated round bar should pass the salt spray tested to at least 48 hours in accordance with ASTM B-117.
Supply Length: Our factory produces chrome plated rod with random length or fixed length up to 12 meters.
