Introduction to precision seamless honed tubes

- Aug 05, 2019-

The seamless mechanical steel pipe for precision machinery is a high-precision seamless steel pipe material after cold drawing or hot rolling. Because the inner and outer walls of precision seamless steel tubes have no oxide layer, high pressure and no leakage, high precision, high smoothness, no deformation of cold bending, flaring, flattening without cracks, etc., they are 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 precision steel pipe is composed of several chemical elements such as carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P and chromium Cr.
