Precision seamless tubes are a high-precision steel material processed by cold drawing or hot rolling. Due to their advantages such as non-oxidized inner and outer walls, pressure resistance without leakage, high precision, high luster, no deformation during cold bending, no cracks during expansion or flattening, they are mainly used to produce products like pneumatic or hydraulic components, such as cylinders, which can be seamless or welded. The chemical composition of precision seamless tubes includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), and chromium (Cr). Compared to round steel and other solid steel materials, precision seamless tubes have the same bending and torsional strength but are lighter in weight, making them an economical section steel. They are widely used in the manufacturing of structural components and mechanical parts.
