What is the meaning of S355J0W, S355J2W, S355k2W corrosion-resistant steel plates

S355J0W, S355J2W, S355k2W are corrosion-resistant steel plates. Implement EN10025 standard. A certain amount of alloying elements, such as P, Cu, Cr, Ni, Mo, are added to the steel to increase the resistance to air corrosion. Under the influence of climatic conditions, an automatic protective oxide is formed on the base metal.

S355J0W, S355J2W, S355K2W corrosion-resistant steel plates delivery status: delivered in hot rolled, normalized or normalized rolled status.

Introduction to S355J0W, S355J2W, S355k2W corrosion-resistant steel plates:
When the steel plate is now marked with "+N or +AR", the specification and heat treatment shall be enforced under the condition of +N or +AR. The flag "+N or +AR" will be added to the steel name and steel number.

Example: Structural steel (S) with improved atmospheric corrosion resistance (W) in the environment with a smaller yield strength of 355MPa and 0 impact energy with a minimum value of 27J Joules (J0) and specification conditions: steel plate EN10025-5-S355J0W+N; or steel plate EN10025-5-1.8959+N (or +AR).
