Precision Bright Tubes are a high-precision steel pipe material processed through precision drawing or cold rolling. Due to their features such as non-oxidized inner and outer walls, ability to withstand high pressure without leakage, high precision, high luster, cold bending without deformation, no cracks upon expansion or flattening, they are primarily used for manufacturing pneumatic or hydraulic components, such as cylinders, which can be either seamless or welded. The chemical composition of Precision Bright Tubes includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), and chromium (Cr).
