Precision seamless tubes are a high-precision steel material processed through cold drawing or hot rolling. Due to their features such as oxide-free inner and outer walls, ability to withstand high pressure without leakage, high precision, high luster, cold bending without deformation, no cracks during expansion or flattening, they are primarily used in the production of 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 products, precision seamless tubes have the same bending and torsional strength but are lighter in weight, making them an economical cross-sectional steel. They are widely used in the manufacturing of structural components and more.
