Oxygen (O) is a harmful element in steel such as A514 grade E structural steel material. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
The company produces and export steel plates and steel section products of various materials all year round. The width of the A514 grade E structural steel material thin plate is 500 - 1500 mm; the width of the thick plate is 600 - 3000 mm. Steel plates are classified by steel type, including ordinary steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, etc .; according to use, there are shipbuilding plate, pressure vessel plate, wear resistant steel plate, bridge builidng steel, corten steel plate, and pipeline steel plate.
BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.
