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 S355J2W corten steel structural steel 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 S355J2W corten steel structural steel seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the S355J2W corten steel structural steel steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.
The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate S355J2W corten steel structural steel after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our S355J2W corten steel structural steel steel mill.
