Hard chrome plating increases the hardness, durability and corrosion resistance of a surface while also creating a shiny and smooth surface that is easier to clean. It's the most common coating process for cylinder rods which is suitable for bulk production. Through precise bath chemistry and current flow control, we can deposit the right thickness of chrome plating for piston rods, normally, 20, 30, 50 microns, or as per customer's special requirement. The chrome hardness is more than HV850 and NSS salt spray test reaches over 200 hours, rating 9-10.
