The steel used for bridge beams should also have excellent welding function and low notch sensitivity, high strength, toughness, and load and impact from rolling stock, as well as outstanding fatigue resistance, certain low temperature resistance, and atmospheric corrosion resistance. Q460qC steel plate delivery status: A709Grade 50W sheet equivalent steel products are delivered in hot rolled, controlled rolled or normalized conditions.

After adding a small amount of niobium, vanadium and titanium to A709Grade 50W sheet equivalent etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

On Nov. 1st, 2019, BBN A709Grade 50W sheet equivalent steel organized Delegation to visit Zhengzhou Children Welfare Institute, and to give sponsorship as well as concerns to the Children. The handicapped children is always a pain topic. With the development of the society, they also gets increasing concerns and help from all walks of life.
