20# precision steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling. Because the inner and outer walls of 20# precision steel pipe have no oxide layer, high pressure and no leakage, high precision, high smoothness, no deformation of cold bending, flaring, flattening without cracks, etc., it is mainly used to produce pneumatic or hydraulic components, such as The cylinder or cylinder can be a seamless tube or a welded tube. The chemical composition of the precision steel pipe includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
