The EN 10025-5 S460J0W Weathering Steel Plate is a high-performance structural material designed for applications demanding strength, impact resistance, and natural corrosion protection. Meeting the European standard EN 10025-5:2004, it delivers a minimum yield strength of 460MPa (for thickness ≤16mm), ensuring robust load-bearing capacity in heavy-duty structures.
Engineered with alloying elements such as copper (0.25–0.55%), chromium, and nickel, this steel forms a stable, adherent rust layer that mitigates further corrosion in atmospheric conditions, reducing reliance on frequent paint or coating maintenance. It undergoes rigorous impact testing at 0℃, with a minimum KV2 value of 27J, ensuring reliable performance in moderate cold environments.
Mechanical properties remain consistent across thicknesses: yield strength decreases slightly with increased thickness (440MPa at 16–40mm, 400MPa at 63–80mm), while tensile strength ranges from 550–720MPa (thin sheets) to 530–680MPa (thicker plates), with an elongation rate of ≥19%. The balanced chemical composition also supports good weldability, though proper procedures (e.g., controlled heat input) are recommended to maintain structural integrity.
Typical applications include railway bridges, freight carriages, industrial steel frameworks, and outdoor infrastructure exposed to moisture, pollution, or varying climates. Its weathering resistance makes it a cost-effective choice for long-term use, minimizing lifecycle costs by reducing corrosion-related repairs. Always verify detailed technical specifications with the standard or suppliers to ensure suitability for specific project requirements.
