Mechanical Seamless Steel Pipe Description
Mechanical seamless steel pipe is a kind of high precision seamless steel pipe material after cold drawing or hot rolling. Due to the precision seamless steel pipe inner and outer walls without oxidation layer, under high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and other points, so it is mainly used for the production of pneumatic or hydraulic components, such as cylinder or cylinder, can be seamless pipe, also welded pipe. The chemical composition of precision steel pipe is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr and more than several chemical elements.
