It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the S960Q EN 10025-6 high strength steel steel industry.

Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than S960Q EN 10025-6 high strength steel, ordinary carbon steel by adding less alloy elements. Q355GNH weathering steel has been widely used in container, railway vehicle, bridge, building and air preheater which need to be resistant to atmospheric corrosion. Q355GNH weathering steel is characterized by the addition of less Cu, P, Cr, Ni and other alloy elements in the steel, so that a dense amorphous spinel type oxide layer with a thickness of about 50-100μm is formed between the rust layer and the base metal, which can prevent oxygen and water from penetrating into the steel matrix, slow down the development of corrosion to steel materials, and improve the atmospheric corrosion resistance.

Bridge steel plate is specially used for erecting railway or highway bridges. S960Q EN 10025-6 high strength steel, bridge steel plate is required to have high strength and toughness to bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate used for bolt welding bridge should also have good welding performance and low notch sensitivity.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled S960Q EN 10025-6 high strength steel products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the S960Q EN 10025-6 high strength steel rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, S960Q EN 10025-6 high strength steel. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.
