S355J2WP is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance. S355J2WP properties main alloying elements are chromium nickel and copper with added phosphorous which gives it excellent self protecting qualities. As the steel reacts with elements in the atmosphere, S355J2WP material machinability, the material forms a layer of rust over time which in essence protects the steel from corrosion. S355J2WP properties Method of deoxidation FF = fully killed steel For long products the P and S content can be 0.005% higher
