Superior Corrosion Resistance
Develops a stable rust layer over time, reducing further oxidation.
Corrosion resistance is 2–8 times higher than ordinary carbon steel in atmospheric conditions.
High Strength & Durability
Yield strength ≥ 265 MPa, ensuring structural stability under load.
Maintains toughness in low temperatures (suitable for -40°C environments).
Cost-Effective Maintenance
Eliminates the need for painting or coatings in many applications, lowering lifecycle costs.
Aesthetic Rust Patina
The reddish-brown oxide layer blends naturally with outdoor environments, often used in architectural designs.
