Precision seamless tubes are a high-precision steel pipe material processed through cold drawing or hot rolling, due to...Precision Steel PipeNo oxidation layer on the inner and outer walls, withstands high pressure without leakage, high precision, high surface finish, cold bending without deformation, expanded mouth, flattened without cracks, etc. Therefore, it is mainly used for producing pneumatic or hydraulic components such as cylinders, which can be seamless tubes or welded tubes. The chemical composition of precision steel tubes includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), and chromium (Cr). Compared to solid steel products like round bars, seamless steel tubes have the same bending and torsional strength but are lighter in weight, making them an economical section steel widely used in manufacturing structural components and mechanical parts.
