Cylinder Tube Made of ST52 - Knowledge

ST52 Cylinder Tube Description

ST52 cylinder tube is a type of high-precision steel tube material processed through cold drawing or hot rolling. Due to its characteristics-such as no oxidation layer on both inner and outer walls, high pressure resistance without leakage, high precision, high surface finish, and no deformation during cold bending, flaring, or flattening without cracks-it is mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders, and can be a seamless tube. The chemical composition of a cylinder tube includes C, Si, Mn, S, P, and Cr.

GNEE Group is a professional manufacturer and exporter of ST52 cylinder tubes, currently exporting to over 150 countries and regions, including Chile, and Kyrgyzstan. As a supplier of ST52 cylinder tubes, we can offer more competitive prices. Additionally, we provide quality inspection services and customisation options, and we support third-party testing.
