S235J0W is an improved weather-resistant structural steel. This steel type is used for welding, bolting and riveting parts. This steel type enhances the ability to resist atmospheric corrosion at ambient temperature. Some specific components are added to achieve corrosion resistance. Alloying elements, such as: P, Cu, Cr, Ni, Mo, etc., form a protective oxide layer on the metal surface under various climatic conditions.
Symbol letter S: structural steel;
For yield strength values with a thickness less than 16 mm: minimum yield value;
J0 is a quality trademark for regular impact energy;
The letter W indicates that the steel has the ability to resist atmospheric corrosion

After adding phosphorus, copper, chromium, nickel and other trace elements into the steel, the steel surface will form a dense and highly adhesive protective film, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer to slow down its corrosion rate. About 50 μ m~100 μ The m thick amorphous spinel oxide layer is dense and has good adhesion with the base metal. Because of the existence of this dense oxide film, it prevents oxygen and water in the atmosphere from infiltrating into the steel substrate, slows down the deep development of corrosion to steel materials, and greatly improves the atmospheric corrosion resistance of steel materials. Weather-resistant steel is a steel system that can be used thinly, exposed or simply coated to make products corrosion resistant, prolong life, save labor, reduce consumption, and upgrade. It is also a steel system that can be integrated into modern metallurgical new mechanisms, new technologies, and new processes to make it sustainable development and innovation.
Due to its excellent corrosion resistance, weathering steel has been widely used in steel structures such as buildings, vehicles, bridges, towers, etc. There are three main ways to use weathering steel: bare use, coating use and rust layer stabilization treatment.
