BKS GB/T 3639 27SiMn carbon steel tubes and pipes & Seamless honed tube for hydraulic cylinder

The honed tube belongs to the high precision steel pipe material, which has no oxidation layer, no leakage of pressure, high accuracy, high finish, no distortion of bending, expansion, and no crack.It mainly applies to machining.The car industry

Honed tube is a kind of high precision steel tube material which is processed by cold drawing or hot rolling.Because of the precision steel tube inside and outside wall without oxidation layer, under high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks etc, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, can be a seamless tube.The chemical constituents of quilted tubes are carbon C, Si, Mn, sulfur S, P and Cr.
