Panneaux en acier corten Q295NH résistant aux intempéries

Performance Characteristics of Q295NH Corten Steel Panels:

1. Weather Resistance:
Self-protecting Rust Layer:
Q295NH forms a stable, oxide layer (patina) when exposed to atmospheric conditions, which prevents further corrosion. This patina develops over time, making the material highly weather-resistant without the need for painting or additional coatings.
Corrosion Resistance:
The steel has improved resistance to atmospheric corrosion compared to regular steel, especially in environments with varying humidity and wet-dry cycles.

2. Mechanical Properties:
Tensile Strength: ≥ 490 MPa
Yield Strength: ≥ 295 MPa
Elongation:≥ 20%
These mechanical properties make Q295NH suitable for high-stress environments while maintaining flexibility and toughness.

3. Impact Resistance:
Impact Energy:≥ 27J at -20°C
This high impact resistance at low temperatures ensures that the steel remains durable in harsh climates.4. High Durability:**
Long Lifespan:
The natural rust layer offers long-term protection, making it suitable for outdoor applications like facades, bridges, and architectural features.
Low Maintenance:
Due to the self-forming protective layer, the need for painting and maintenance is minimal.

5. Weldability:
Q295NH has good weldability, making it easy to fabricate and integrate into large structures. Proper welding techniques should be employed to maintain the weather-resistant properties.

6. Atmospheric Adaptability:
Adaptable to Harsh Climates:
The steel performs well in both dry and wet environments and can withstand UV radiation and pollution.
Patina Development:
The patina develops faster in alternating wet and dry environments, offering improved protection over time.

7. Aesthetic Appeal:
Natural Weathered Look:
The rusted surface has an appealing, rustic look that is highly desirable in architectural and landscaping applications.

8. Environmental Benefits:
Sustainability:
By eliminating the need for paint or coatings, Q295NH is considered more environmentally friendly. The patina reduces the steel’s degradation, extending its life cycle and reducing the need for replacements.
