Effect of cooling process on microstructure and properties of EN steel grade S235J2 plates

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the EN steel grade S235J2 plates steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of EN steel grade S235J2 plates seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

Carbon steel pipe is more often used than alloy steel pipes. Compared with alloy steel pipe, It has the advantage of good performance with lower cost. BBN supplies EN steel grade S235J2 plates most often used carbon steel pipes and tubes of comprehensive grades and specifications. According to its production process, Including seamless steel pipe, erw steel pipe and spiral welded steel pipe.
