Precision steel tube is a high-precision steel material treated after drawn or rolled. Precision steel tube outer wall as no oxide layer, withstand high pressure without leakage, high precision and high finish, cold deformation, flaring, flattening a bit without cracks, so it is mainly used to produce pneumatic or hydraulic components such as cylinders or cylinder, which can be seamless, but also welded pipe (after cold treatment). Precision steel's main chemical composition is Fe, C, Si, Mn, S, P, Cr and so on. Precision steel tubes appear in recent years, has a strict requirement of tolerances and roughness in the inner and outer wall. Features of Cold drawn (rolled) precision steel tubes 1. Smaller Diameter. 2. Small MOQ. 3. High precision, good surface quality. 4. Better performance.
