These chrome plated bars find application in a wide range of industries, including industrial machinery, automotive, and aerospace sectors.
Hard Chrome Shaft
Material: Hard chrome shafts are typically produced from medium carbon cold-finished or hot rolled steel bars, commonly in grades such as 1045. These grades of steel provide good strength and durability for piston rod applications.
Manufacturing Process: The bars undergo a series of manufacturing processes to achieve the desired properties. These processes include centerless grinding, polishing, and hard chrome plating.
Centerless Grinding: The bars are centerless ground to ensure precise dimensions and a smooth surface finish. Centerless grinding removes any imperfections and ensures the bars meet specified tolerances.
Polishing: After grinding, the bars undergo a polishing process. Polishing further improves the surface finish, providing a smooth and uniform appearance. This step contributes to the overall quality and aesthetics of the chrome plated bars.
Hard Chrome Plating: The final step in the manufacturing process is hard chrome plating. The bars are immersed in a plating bath, where a layer of hard chrome is deposited on the surface. The chrome plating provides excellent corrosion resistance, wear resistance, and durability.
Minimum Chrome Thickness: Hard chrome shafts have a minimum chrome thickness of 0.0005" (0.0127mm) and 0.001" (0.0254mm) per side. This ensures a sufficient layer of chrome for the desired properties and performance.
