S355J2WP Weathering Steel Plate 6mm 8mm 12mm EN 10025-5 Atmospheric Corrosion Resistant Sheet

S355J2WP Weathering Steel Plate

S355J2WP is a structural weathering steel defined by EN 10025-5. The added phosphorus, together with copper, chromium and nickel, delivers improved atmospheric corrosion resistance, while the J2 impact class guarantees toughness at -20 deg C. The surface develops a dense, adherent rust layer that protects the steel and slows further corrosion, making it ideal for bare, unpainted outdoor structures.

Key Features

• Improved atmospheric corrosion resistance per EN 10025-5
• Yield strength from 355 MPa with good weldability
• Charpy V-notch impact energy 27 J at -20 deg C (J2 quality)
• Long service life with low maintenance in outdoor environments
• Attractive weathering patina for architectural applications
