After adding a small amount of niobium, vanadium and titanium to A514 Gr E alloy steel plate 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.
Compared with thick steel plates, A514 Gr E alloy steel plate, thin steel plates have many obvious advantages in steel plate processing and use. It is precisely these advantages of thin steel plates that make them more and more popular in various industries. First, compared to those thicker steel plate materials, thin steel plates are generally thinner in thickness. Thin steel plates themselves are lighter and thinner, and their weight is lighter, which is very convenient for handling during construction and transportation. It can save some storage and transportation space.
EN10025-2 S235J2 steel is equivalent to our Chinese teel grade Q235D. They are both done low temperature impact test at -20℃. Sometimes S235J2 would be used to built containers which can bear low temperature sea water. A514 Gr E alloy steel plate, S235J2+N steel plate, following a rolling process within a certain temperature range, producing a material in a condition equivalent to that obtained after normalization. With the result that the specified mechanical properties values are conserved even after normalization treatment.
Our company was founded in 2000, which initially committed to providing high-quality steel A514 Gr E alloy steel plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export A514 Gr E alloy steel plate steel to the international market, opening up the international steel market.
