A high-precision steel pipe material processed by cold drawing or hot rolling, featuring internal and external walls without oxidation, pressure resistance without leakage, high precision, high luster, easy cold bending without deformation, no cracks during expansion or flattening, and other advantages, is mainly used for producing products like pneumatic or hydraulic components, such as cylinders, which can be seamless or welded pipes. The chemical composition of the precision drawn steel pipes includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), and chromium (Cr). Compared to solid steel materials like round bars, precision drawn steel pipes have the same bending and torsional strength but are lighter in weight, making them an economical cross-sectional steel suitable for large-scale manufacturing of structural components and mechanical parts.
