S355J0WP is a structural weathering steel which is also referred to as atmospheric corrosion resistant steel. S355J0WP the 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, the material forms a layer of rust over time which in essence protects the steel from corrosion.
S355J0WP steel rusts when exposed to atmospheric elements, the S355J0WP steel builds its own protective layer, which prevents the steel from further oxidation, because of containing alloying elements, such as Chromium, copper ect.. Therefore, due to materials’ aesthetically pleasing finish (oxidation), S355J0WP used in steel sculptured buildings. Meanwhile, the S355J0WP steel cuts down the costly need for painting or external treatment.
S355J0WP Steel Delivery Condition: Controlled Rolling, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP).
