Production Process Of E355 Seamless Honed Tube
E355 seamless honed 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. E355 honed tubes mainly used for pneumatic or hydraulic components, such as cylinder barrels , can be seamless pipe. The chemical composition of the quilted grinding tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr. PROCESSING TECHNOLOGY OF E355 SEAMLESS HONED TUBES E355 honed tube is processed by rolling, because the surface layer has residual compressive stress on the surface, which helps to close the tiny cracks on the surface and hinders the expansion of erosion. Therefore, the corrosion resistance of the surface can be improved, and the generation or expansion of fatigue c...
