• S355J0W Steel Description

  S355J0W steel is a weather resistant steel which could more accurately be termed as an "Atmospheric Corrosion Resistant Steel" and often referred to as Corten-B steel. Weathering means that due to S355J0W steel chemical compositions, S355J0W steel chemical composition can increase resistance to atmospheric corrosion compared to other steels. This is because it forms a protective layer on S355J0W steel surface under the influence of the weather.

  S355J0W steel Deliver condition

  Hot Rolled, Cold Rolled, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP), Electroslag Remelting Technical, HIC test.

• S355J0W steel Application range

  The S355J0W steels are used for various types of welded, bolted and riveted constructions e.g. steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions and so on.

  Note: 1. The steels may show a Ni content of max 0.65 %; 2. For long S355J0W steel, the P and S content can be 0.005% higher; 3. The S355J0W steel may contain max. 0.30 % Mo and max. 0.15 % Zr 4. It is permissible to exceed the specified values provided that for each increase of 0.001 % N, the P max. content will be reduced by 0.005 %; the N content of the ladle analysis, however, shall not be more than 0.012 % 5.The max. value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0.020 % or if sufficient other N binding elements are present.
