Specifications of Precision Steel Pipe
Precision steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Due to the inner and outer walls of precision steel pipes have no oxide layer, high pressure without leakage, high precision, high smoothness, cold bending without deformation, flaring, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic components, such as cylinders, could be a seamless tube or a welded tube. The chemical composition of precision steel pipes includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
