The difference in application
S235J0 European standard carbon structural steel, 0°C impact, EN 10025-2 S235J0 steel is used to manufacture welding, bolting and riveting structures. S235J0W grade is a weather-resistant structural steel improved on the basis of S235J0. S235J0W steel plate is used for welding, bolting and riveting parts. This steel grade enhances the ability to resist atmospheric corrosion at ambient temperature. It is added in order to achieve corrosion resistance. Certain specific alloying elements, such as P, Cu, Cr, Ni, Mo, etc., form a protective oxide layer on the metal surface under various climatic conditions.
