EN 10025 S355J2W+N: Europeanstandard S355J2W+N grade for weatherresistant steel plates: CORTEN B is weatheringsteel with improved atmospheric corrosion resistance. Due to its chemicalcomposition, this material develops a patina with increased resistance againstthe atmospheric corrosion in comparison with non-alloyed steels. Due to itsrestricted chemical composition, S355J2W STEEL has a better weldabilitycompared to respective steels produced according to EN 10025-5. S355J2W+N weather-resistant structural steel grade isused for various types of welded, bolted and riveted constructions e.g. steelframe structures, bridges, tanks and containers, exhaust systems, vehicles andequipment constructions.
