EN 10155 S355J0W Weathering Steel Plate

S355J0W steel is a weathering steel, more accurately known as "atmospheric corrosion resistant steel", often referred to as Corten-B steel. Weathering resistance is due to the chemical composition of S355J0W steel, which improves resistance to atmospheric corrosion compared to other steels.

S355J0W steel can be used in a variety of welded, bolted and riveted structures, such as steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment structures.
