S355J0W, S355J2W, S355K2W steel plate executive standard: EN10025-5: 2004 standard.
S355J0W, S355J2W, S355K2W steel plate delivery status: delivered in hot rolled, normalized or normalized rolled state.
Grade S355J0W, S355J2W, S355K2W belong to the European standard atmospheric corrosion resistant steel, which is a weather resistant steel plate. It is a low alloy steel made by adding a certain amount of alloying elements to ordinary steel. The atmospheric corrosion resistance of weathering steel is 2-8 times that of ordinary carbon steel, and it has good mechanical properties and welding properties. The longer the time, the more obvious the corrosion resistance.
What are the differences among the S355J0W, S355J2W, S355K2W steel?

S355J0W, S355J2W, and S355K2W steel plates are weathering steels, that is, atmospheric corrosion-resistant steels. They are low alloy steel series between ordinary steel and stainless steel. Weathering steel is mainly used for steel structures exposed to the atmosphere for a long time, such as railways, vehicles, bridges, towers, photovoltaics, and high-speed projects.
