What is the composition performance of S355J2W steel

S235J0W, S235J2W, S355J0WP, S355J2WP, S355J0W, S355J2W, S355K2W are main EN series weather resistant steel gardes. When the product is forcibly specified and delivered in the condition of +N or +AR, the sign "+N or +AR" will be added to the steel name and steel number. Example: Structural steel (S) with improved atmospheric corrosion resistance (W) at ambient specified minimum yield strength of 355MPa and 0 impact energy minimum of 27J Joules (J0) and standard rolled delivery conditions: steel plate EN10025-5-S355J0W+N; or steel plate EN10025-5-1.8959+N (or +AR).

S355J2W steel implements standard EN10025.
S355J2W steel delivery condition: hot rolled, normalized or normalized rolled.
