Honed steel tube is a kind of high-precision steel pipe material processed by cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of the precision steel tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as cylinders or Cylinder, can be seamless pipe. The chemical composition of honed steel tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr. Have you ever understood the processing technology and processing principle of honed steel tubes? Let me find out together!

The honed steel tube is processed by rolling. Since the surface layer has residual compressive stress on the surface, it can help close the tiny cracks on the surface and prevent the expansion of the erosion effect. Therefore, the corrosion resistance of the surface is increased, and the generation or expansion of fatigue cracks can be reduced, thereby increasing the fatigue strength of the honed steel tube. Through roll forming, a cold work hardened layer is formed on the rolled surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair and prevents damage caused by grinding. After rolling, the surface roughness value decreases, which can increase the mating properties.
