Product Description

Precision seamless tube is a kind of high precision steel tube material through cold drawing or hot rolling treatment, because of the advantages of precision steel tube inside and outside wall without oxide layer, no leakage under high pressure, high precision, high finish, cold bending without deformation, flaring, flattening without cracks, etc., so it is mainly used for the production of pneumatic or hydraulic components products, such as cylinders or cylinders, which can be seamless tubes, but also welded tubes Precision Steel Tube Chemical Composition.
