Product Description

About products

Chromium plated rod refers to a layer of chromium with a hardness of 50-60 formed by electroplating on the surface of a hard optical shaft, which is suitable for matching use in the automation industry and linear bearings. The surface of a chrome plated rod looks like a rod product, but its application range is still very wide. In addition, there is a layer of chrome plated layer on its surface, which has characteristics such as abrasion resistance, corrosion resistance, heat resistance, etc. It can also increase the hardness and finish of the surface
Chromium plated rod is not only suitable for supporting the use of linear bearings in the automation industry, but also can be applied to many types of guide rods, operating rods, adjusting rods, transmission shafts, pillars, cylinders, cylinders, die-casting machines, injection molding machines, fitness equipment, electronic equipment, electric tools, precision machinery, packaging machinery, printing machinery, woodworking machinery, textile machinery, printing and dyeing machinery, light industry machinery, engineering machinery, mining machinery Used in automation equipment and other various industrial machinery and supporting equipment

Application

This is a kind of carburizing steel with good properties. Its characteristics are similar to those of 20CrMnTi and 20CrNi steels. It has high strength, wear resistance and hardenability. The critical quenching diameter in oil is 27~53mm. The machinability, carburizing and heat treatment process properties of the steel are good. There is no tendency of grain growth when carburizing for a long time at high temperature, and the carbon concentration distribution in the carburized layer decreases gently, which will not cause sudden changes in the structure and properties. It can also be directly cooled and quenched after carburizing; Compared with 20CrMnTi steel, its disadvantages are large quenching deformation and more decarburization. This steel can be used as a substitute for 20CrMnTi, 20Cr and 20CrNi. Used to manufacture medium and small carburized parts with large modulus and heavy load. Such as: gears and shafts on heavy machine tools, driving and passive gears on the rear axle of automobiles, etc.
