The material of DIN2391 is precision seamless steel pipe. Precision seamless steel pipe is a high-precision steel pipe processed by cold rolling or cold drawing; the full name is: cold rolled or cold drawn precision seamless steel pipe. Due to the advantages of no oxide layer on the inner and outer walls of the precision seamless steel pipe, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as Cylinders or oil cylinders are made of seamless pipes. The chemical composition of precision seamless steel pipe is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
