Chrome Plated Bar Processing Technology
Sep 19, 2017

The chrome plated bar is rolled by rolling, because the surface layer has residual compressive stress on the surface, which is helpful to the sealing of small cracks on the surface and hinders the expansion of erosion. Thereby, the surface corrosion resistance can be improved, and the generation or expansion of fatigue cracks can be delayed, thereby improving the fatigue strength of the cylinder rod. Chrome bar through rolling, rolling surface to form a layer of cold hardening layer, reduces the grinding contact surface of the elastic and plastic deformation, thus improving the wear resistance of the cylinder rod surface, while avoiding grinding burns caused by. When the chromium plated rod is rolled, the surface roughness decreases, and the compatibility can be improved.
