Technical Specifications for S355J0WP Weathering Steel Plate

S355J0WP is a high-strength, low-alloy structural steel resistant to atmospheric corrosion, conforming to the European standard EN 10025-5, with the material designation 1.8945. It is a cost-effective weathering steel for outdoor, uncoated structural projects. As a core grade in the EU weathering steel series, it combines high mechanical strength, stable low-temperature toughness at 0°C, and the ability to form a self-protective rust layer, distinguishing it from ordinary carbon structural steel and other lower-grade weathering steels.
