Precision seamless steel pipe is a cold drawn or hot-rolled after treatment of a high-precision steel pipe. As the precision seamless steel pipe inside and outside the wall of non-oxidized layer of precision seamless steel pipe, to withstand high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks, etc., is mainly used to produce pneumatic or hydraulic components Of products, such as cylinders or cylinders, are made of seamless tubes. Precision seamless steel pipe chemical composition of carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
