Weathering steel plate Q500NH, Q550NH weather resistant steel price for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate Q500NH, Q550NH weather resistant steel price has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.
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 Q500NH, Q550NH weather resistant steel price 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 Q500NH, Q550NH weather resistant steel price seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous Q500NH, Q550NH weather resistant steel price pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.
