Q550NHコールテン鋼板

Q550NH Corten Steel Plate is another high-strength low-alloy (HSLA) steel, similar to other corten or weathering steel grades, but with a higher yield strength than Q450NQR1. It’s specifically designed for use in structural applications that require both strength and corrosion resistance in atmospheric environments.

Key Features of Q550NH Corten Steel Plate:

1. High Yield Strength: The “550” indicates a yield strength of 550 MPa, making it ideal for heavy-duty structural uses.
2. Corrosion Resistance: Like other corten steels, Q550NH forms a stable, self-protecting oxide layer when exposed to atmospheric conditions, reducing the need for painting or coating.
3. Toughness and Durability: Suitable for use in harsh environments, such as industrial zones and outdoor settings where longevity is crucial.
4. **Low Maintenance: The weathering steel’s rust layer serves as protection, reducing the need for upkeep over time.
5. Enhanced Weldability: Its alloy composition allows for ease in welding, making it versatile in construction and fabrication.

Typical Applications:
– Bridges and structural supports
– Outdoor architectural elements
– Garden and landscape structures
– Building facades and cladding
– Industrial infrastructure like silos, chimneys, and power plants
– Shipping containers and transport vehicles

Q550NH Corten Steel Plate is ideal when high strength and corrosion resistance are both critical. Let me know if you’d like more specific information or applications!
