Key Performance Features

1. Superior Weathering Resistance

Patina Formation: Alloying elements (Cu, P, Cr) promote the growth of a dense, adherent rust layer (α-FeOOH) that acts as a barrier against moisture and oxygen, reducing corrosion rates by 5–8 times compared to carbon steel.

Environment Suitability: Ideal for industrial atmospheres (e.g., urban/coastal areas) or structures exposed to pollution, salt spray, or humidity.

2. Excellent Weldability

Low Carbon Equivalent: Minimizes risk of hydrogen-induced cracking during welding.

Welding Methods: Compatible with common techniques (SMAW, GMAW, SAW) without preheating for most applications.

3. Fabrication Flexibility

Forming: Easily cut, bent, or machined into complex shapes for architectural or structural applications.

Post-Processing: No special treatment required after fabrication; patina develops naturally over time.

Dimensions and Customization

Thickness: 8–200 mm (standard range; custom thickness available).

Width: 1,500–4,020 mm.

Length: 6,000–18,800 mm.

Tailored Solutions: Custom rolling, cutting, and heat treatment available per project specifications.
