EN 10025-5 S420J0W High Strength Weather Resistant Steel Plate
Engineered to meet EN 10025-5 standards, the S420J0W steel plate combines high mechanical strength with superior atmospheric corrosion resistance, making it a prime choice for demanding outdoor applications.
Key Features
High Strength & Robustness: With a minimum yield strength of 420 MPa and tensile strength ranging 500–680 MPa, it supports heavy loads in critical structures like bridges, industrial frameworks, and transportation equipment.
Exceptional Weather Resistance: Alloyed with copper, phosphorus, chromium, and nickel, it forms a dense, adherent oxide layer (patina) that slows rust penetration, eliminating frequent painting and reducing lifecycle costs.
Cold-Weather Reliability: The "J0" designation ensures passing impact tests at 0°C (≥27J), making it suitable for regions with moderate 低温 climates.
Fabrication-Friendly: Easily welded, cut, and machined using standard techniques, aligning with conventional structural steel processes for efficient manufacturing.
Applications
Civil Infrastructure: Bridges, railway systems, and architectural steelwork exposed to rain, humidity, or pollution.
Transportation: Container bodies, truck frames, and railway carriages requiring corrosion resistance during outdoor use.
Industrial Equipment: Storage tanks, pipelines, and offshore structures in harsh coastal or industrial environments.
