A606 Corten
A606 Corten steel offers an excellent balance of resistenza alla corrosione, formabilità, and aesthetic appeal. Its alloy composition allows it to develop a strato di ruggine autoprotettivo, making it a preferred material for architectural design, landscaping products, and outdoor sheet metal applications.
- Descrizione
A606 Corten steel (ASTM A606) è un ad alta resistenza, bassolegato (HSLA) weathering steel sheet widely used in architectural and outdoor applications. It is especially known for its ability to develop a stable rust patina, which protects the material from further corrosion.
Chemical Composition of A606 Corten
The composition of A606 steel is designed to enhance atmospheric corrosion resistance:
| Elemento | Contenuto (%) |
|---|---|
| Carbonio (C) | ≤ 0.22 |
| Silicio (E) | ≤ 0.40 |
| Manganese (Mn) | ≤ 1.35 |
| Fosforo (P) | ≤ 0.04 |
| Zolfo (S) | ≤ 0.05 |
| Rame (Cu) | ≥ 0.20 |
| Cromo (Cr) | ≤ 0.50 |
| Nichel (In) | ≤ 0.50 |
Key Alloying Elements
-
Rame (Cu): Migliora la resistenza alla corrosione
-
Cromo (Cr): Migliora la resistenza all'ossidazione
-
Nichel (In): Increases durability in harsh environments
Proprietà meccaniche
| Proprietà | Valore tipico |
|---|---|
| Yield strength | ≥ 345 MPa |
| Resistenza alla trazione | 450 – 620 MPa |
| Allungamento | ≥ 18% |
Caratteristiche chiave
1. Resistenza alla corrosione atmosferica
A606 develops a protective oxide layer when exposed to air and moisture, reducing long-term corrosion rates.
2. Good Formability
-
Adatto per flessione, rolling, e formando
-
Ideal for thin sheet metal fabrication
3. Aesthetic Rust Finish
-
Forma a uniform orange-brown to dark brown patina
-
Widely used for decorative and architectural purposes
4. Manutenzione ridotta
-
No need for painting or coating in most outdoor environments
-
Long service life with minimal upkeep
