What is the smelting process of S235J2W bridge structural steel

Our technical department plays important role in our professional communication with customers, especially those who have high technical requirements for steel materials and those who need complex further processing. Under such condition, our technician department can provide technical support in time, anylize customer design or make drawing according to customer needs rapidly, so that we can proceed smoothly. The profession of our team has won great praise of customers.

S235J2W bridge structural steel, Wear resistant steel plate is widely used, sometimes it needs to be bent, rolled and cut. Since the wear resistant layer is closely combined with the base plate through metallurgical processing, there is no problem with bending and rolling the wear resistant steel plate under normal conditions. However, if the rolling diameter is less than 300 mm, it will cause problems, so it is not recommended to roll under 300 mm.

Most common S235J2W bridge structural steel steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled S235J2W bridge structural steel steel plates.
