Owning to the minimum 355 Mpa yield strength,S355K2W atmospheric corrosion resistance steel plate shall be the highest steel grade in steel standard specificaiton EN 10025-5,and additionally the low temperature impacting test for weahering steel plate S355K2 have to be done with minimum 40J impacting energy at minus 20 celsius degree.
S355K2W weathering steel plate is a high strength low alloy steel which is suitable environments forms an adherent protective rust oatina to prevent further corrosion.So steel sheet S355K2W ispopularly used in outdoor sculptures,brige,main structural applications and also widely in marine transportation which shall be in the construction of intermodal shipping containers.Normally for improved these weathering steel plates' perperity,the brige engineers still want steel plate S355K2W to be done Normalized when rolling,we named this steel as S355K2W+N,also have other steel grades S355J2W+N,S355J0W+N.These steels are commonly used for brigeworks in UK.
