Q550NQR1 Hot Rolled Plates

Q550NQR1 steel is a kind of corrosion-resistant steel or weathering steel. BBN steel can produce Q550NQR1 hot rolled plates which meets the standard requirements. Fine and uniform microstructure is a prerequisite for good low temperature impact toughness, and acicular ferrite structure can guarantee high impact toughness at low temperatures.

Characteristics of hot rolled Q550NQR1 corrosion-resistant steel 

1. Q550NQR1 hot rolled plates have outstanding visual expression. Corroded steel sheets change over time. Its color brightness and saturation are higher than the general structure materials, so it is easy to stand out under the background of garden green plants. In addition, the rough surface created by the corrosion of the steel plate makes the structure more bulky and quality.
2. It has a strong physical shaping ability. Like other metal materials, corroded steel sheets are easier to shape into a variety of shapes and maintain excellent integrity, which is difficult to achieve with wood, stone and concrete.
3. It also has a clear spatial definition ability. Since the strength and toughness of the steel sheet are large, it is not as much as the thickness limitation of the masonry material due to the structure. Therefore, the space can be clearly and accurately separated by a very thin steel plate, making the site simple, bright and full of power.

Application of Q550NQR1 steel plates

1. High-performance weathering steel and heat-resistant steel can reduce the maintenance cost of steel structure and provide a new solution to solve the fire and corrosion problems of unprotected steel structures such as high-pressure towers.
2. The manufacturing and installation process of fire resistant weathering steel is basically the same as that of conventional steel, and its design method is the same as that of ordinary steel structure. However, more experimental verification is needed.
3. High-strength weathering steel has a wide range of applications in bridge engineering. It is necessary to study design theories and methods.
4. Q550NQR1 weathering steel can also be used for floors.
