High tensile steel grade hardox 400 equivalent suppliers

European standard high strength EN10025-6 S690QL steel plates are designed to provide excellent welding and bending properties. Due to its high strength, it enables design of lighter, more durable and efficient products and structures with S690QL steel plates and HARDOX 400 equivalent.The company has HARDOX 400 equivalent advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience HARDOX 400 equivalent, we have accumulated a large number of customers at home and abroad, and won unanimous praise.The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the HARDOX 400 equivalent steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the HARDOX 400 equivalent steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.After adding a small amount of niobium, vanadium and titanium to HARDOX 400 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.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, HARDOX 400 equivalent 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!
