S420NL carbon steel plate sheet size as required

High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the S420NL carbon steel plate sheet, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.

Q420q material is a kind of structural steel plate for bridges, and there are three quality levels Q420qD, Q420qE and Q420qF. When the Q420q plate is required to have the performance in the thickness direction, the symbols Z15, Z25, Z35 representing the performance level in the thickness direction are added after the above-mentioned grades. Namely Q420qDZ15, Q420qDZ25, Q420qDZ35, Q420qEZ15, Q420qEZ25, Q420qEZ35, Q420qFZ15, Q420qFZ25, Q420qFZ35.

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel S420NL carbon steel plate sheet products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the S420NL carbon steel plate sheet market and has strong competitiveness.

After adding a small amount of niobium, vanadium and titanium to S420NL carbon steel plate sheet 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.
