Oxygen (O) is a harmful element in steel such as P355GH steel size. 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.

Leading by innovation, both parties of the BBN Steel Group give full play to the location advantages of clean energy, implement solid implementation, and steadily realize low-carbon transformation, achieve "carbon peak" as soon as possible, and move toward "carbon neutrality".
