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.

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.
FAQ
Q: What is the equivalent of S355J0W?
A: The equivalent grade of S355J0W under NFA 35-502 standard is E 36 WB 3. And S355J0W equivalent grade of BS4360 standard is WR 50 B. S355J0W equivalent grade of ISO 4952 standard is Fe 355 W.
Q: What is Characteristics of S355J0W steel?
A: Excellent atmospheric corrosion resistance: S355J0W steel adds a small amount of corrosion resistance elements such as copper and nickel on the basis of ordinary steel, which can form a dense protective film on the surface of the steel plate and effectively resist corrosion factors in the atmosphere, such as moisture, oxygen and pollutants. Therefore, the atmospheric corrosion resistance of S355J0W steel is 2 to 8 times that of ordinary carbon steel, and it has a long service life.
