EN 10025-5 Weathering Steel S355J2WP

S355J2WP grade steel is a hot rolled product of structural steel under technical conveying conditions, with better resistance to atmospheric corrosion.

S355J2WP steel plate trademark analysis:
Steel Designations and Steel Numbers: Steel designations include:
S—symbol S (for structural steel);
355—Description of the lower limit yield strength of the rule for thickness £ 16mm, expressed in MPa);
J2—Quality title based on impact energy data;
W—indicates that the steel is of improved atmospheric corrosion resistance;
P - if applicable, the letter P is used for the greater phosphorus content classification (only when the steel grade is S355);

The main alloying elements of S355J2WP grade steel 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.
