Products Description
S355J0W steel is a kind of weathering steel, also known as atmospheric corrosion resistant steel, is a low alloy steel series between ordinary steel and stainless steel.
This steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion resistant elements, so that it has stronger weather resistance than ordinary steel.
In the grade representation of S355J0W steel, "S" stands for structural steel, "355" stands for the lowest yield strength of 355MPa when the thickness is less than or equal to 16mm, "J" stands for the quality identifier of the relevant impact work value, "0" stands for 0℃ impact test, and "W" stands for the resistance of steel to atmospheric corrosion. The standard of S355J0W steel plate is EN10025-5:2004.

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.
