09CuPCrNi-B Corten Steel Plate

09CuPCrNi-B is another widely adopted corten-equivalent steel, with slightly higher strength and better low-temperature performance than its -A counterpart. Manufactured according to GB/T 4171, this grade is often used in structural, bridge-building, and outdoor engineering applications.

It offers reliable resistance to atmospheric corrosion and excellent mechanical performance, especially in industrial and heavy-load environments.

🌟 Key Advantages

• Enhanced corrosion resistance under cyclic wet/dry conditions

• High tensile and yield strength

• Suitable for welding and structural fabrication

• Ideal for industrial exposure and unpainted use

• Compatible with pre-rusting or weathered surface treatments

🛠 Common Applications

• Bridges and load-bearing structural parts

• Heavy-duty shipping containers

• Industrial steel towers and platforms

• Marine engineering and offshore use

• Garden corten edging and wall panels
