Weathering Steel S355J2WP Application

Weathering Steel S355J2WP Application

S355J2WP steel is a structural steel hot-rolled product under technical conveying conditions, with better atmospheric corrosion resistance. The main alloying elements are chromium nickel and copper plus phosphorus, which have excellent self-protection properties. As it reacts with elements in the atmosphere, the material develops a layer of rust over time, which essentially protects the steel from corrosion.

Corrosion resistant steel sheet S355J2WP under EN 10025_5 is mainly used for vessel steel. With good atmospheric corrosion resistance, S355J2WP can often be seen in buildings, chimneys, manufacturing, trucks, silos, towers and bridges.

S355J2WP steel is alloyed with copper and chrome to ensure a firmly adherent rust protection layer while maintaining an aesthetically pleasing appearance.
