What is a chrome rod?

Chrome-plated rod refers to a rod with a layer of chromium element with a hardness of 50-60 formed on the surface of the hard optical axis by electroplating. It is suitable for use in automation industry and linear bearings. Chrome-plated rod refers to a rod with a layer of chromium element with a hardness of 50-60 formed on the surface of the silver steel branch by electroplating. It is suitable for use in automation industry and linear bearings. Chrome rod is a material. The optical axis is a simple part. Piston rod is a kind of mechanical part, which can be assembled, and the material is also very different. Where is the chrome-plated rod used. Bearings are widely used in the bearing industry. Generally, low-cost 45 round steel is used as the body, and the surface is plated with hard chromium 15-30 microns to improve its wear resistance. In daily life, the common tolerance of chrome-plated rods is g6 or h7, and the thickness of chrome-plated is 0.8~3mm. A3 steel is a name in the past, and now it is called Q235 steel, with a yield strength of 235MPa and a tensile strength of 375-460MPa; Elongation 26%. In the board, Q235 is the most common material, belonging to the general board series.
