S355J0W sheet is widely used in high-speed rail bogies, welding, bolting and riveting parts. S355J0WP steel plate enhances the ability to resist atmospheric corrosion at ambient temperature. In order to achieve corrosion resistance, certain alloy elements are added, such as: P, Cu, Cr, Ni, Mo. Under various climatic conditions A protective oxide layer is formed on the metal surface.
