The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, S355J2WP rusty steel Chinese supplier tube.
High weather resistance structural steel Q295GNH, Q355GNH adds a small amount of alloying elements such as Cu, P, Cr, Ni, etc. to form a protective layer on the basic surface of the metal to improve the steel with atmospheric corrosion resistance. High weather resistance structural steel is mainly used in the structure of vehicles, containers, buildings, towers or other structural parts. Compared with welded structural steel S355J2WP rusty steel Chinese supplier, it has better atmospheric corrosion resistance.
