Chrome Plated Hollow Bar Introduction

Chrome Plated Hollow Bar is mainly used for hydraulic pneumatic, construction machinery, automobile manufacturing piston rod. The piston rod is processed by rolling pressure, because the surface layer has residual compressive stress on the surface, which helps to seal the surface micro-cracks and hinder the expansion of erosion. Therefore, it can improve the surface anti-corrosion ability and delay the production or expansion of fatigue cracks, thus improving the fatigue strength of oil cylinder.
