NM400 use for bridge main useage

The advantages of NM400 use for bridge, medium and thick boiling steel plate: The surface is relatively smooth, the quality is good, and it is easy to process. Because medium and thick boiling steel plate does not have concentrated shrinkage holes, the amount of deoxidizer is small, and boiling steel plate price is lower than other steel plates. Disadvantages of medium and thick boiling steel plate: it has a lot of gas content and impurities, it is not easy to weld, and its bearing capacity is worse than other steel plates, so it is not suitable for parts that need to bear gravity.

Our company has NM400 use for bridge strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply NM400 use for bridge deep processing service for products NM400 use for bridge like cutting, drilling, bending, welding and grinding.

"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, NM400 use for bridge Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach NM400 use for bridge 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual NM400 use for bridge production capacity: 3.5 million tons."

Modern steel-making steel purification facilities and advanced quality control methods have been perfected. Rolling steel can be produced according to controlled rolling and controlled cooling, normalizing, and quenching and tempering processes to produce σs 390-685Mpa series products. NM400 use for bridge, Low alloy high strength structural steel plate has stable quality, good wear resistance and low temperature toughness. It can be widely used in the manufacture of mining machinery, engineering machinery, high-rise buildings and heavy vehicles.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, NM400 use for bridge sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
