Precision seamless tube is a high-precision steel pipe material processed by cold drawing or hot rolling, due to...Precision steel tubesInternally and externally non-oxidized, withstands high pressure without leakage, high precision, high surface finish, cold bending without deformation, expandable, flattening without cracks, etc. Therefore, it is mainly used for producing pneumatic or hydraulic components such as cylinders, which can be seamless or welded pipes. The chemical composition of precision steel pipes includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), and chromium (Cr). Compared to solid steel materials like round bars, seamless steel pipes have the same bending and torsional strength but are lighter in weight, making them an economical cross-section steel widely used in the manufacturing of structural components and mechanical parts.
