EN 10025-5 — Hot rolled products of structural steels. Part 5: Structural steels with improved atmospheric corrosion resistance
Scope
Weathering (Cu-Cr-Ni-P) structural steels that form a protective rust patina: S235J0W, S235J2W, S355J0W, S355J2W, S355K2W and the phosphorus variants S355J0WP/J2WP, as plate, strip, sections and bar. Chemistry (Cu 0.25–0.55, Cr 0.40–0.80), mechanical properties by thickness, impact by quality, delivery conditions; the European home of the material sold as Corten A/B.
