After adding a small amount of niobium, vanadium and titanium to A514 Gr T 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.

Management information and high efficiency. Because of the rapid flow of A514 Gr T alloy steel plate goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
According to different purposes, the thin steel sheets are rolled from billets of different materials. Commonly used materials include plain carbon steel, such as A514 Gr T alloy steel plate, high-quality carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, and silicon steel for electrical purposes. The thin steel sheets are mainly used in the automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and other sectors. In addition to delivery directly after rolling, there are also pickled, galvanized and tinned thin steel sheets.
