2205 Hoja
2205 duplex stainless steel sheet is a high-strength, corrosion-resistant material with a balanced duplex microstructure, making it one of the most widely used stainless steels in industrial environments. comparado con 2507 super duplex stainless steel, 2205 offers a more economical solution while still providing excellent mechanical strength and corrosion resistance for most engineering applications.
- Descripción
2205 duplex stainless steel sheet is one of the most widely used duplex stainless steels, combinatorio austenitic and ferritic phases in its microstructure. This dual-phase structure gives it a unique balance of alta resistencia, excelente resistencia a la corrosión, and good stress corrosion cracking resistance.
Composición química de 2205 Acero inoxidable
2205 is designed with higher chromium and molybdenum content compared to standard austenitic grades.
| Elemento | Contenido (%) | Función |
|---|---|---|
| Cromo (cr) | 21–23% | Resistencia a la corrosión |
| Níquel (En) | 4.5–6.5% | Stabilizes duplex structure |
| Molibdeno (Mes) | 2.5–3.5% | Pitting corrosion resistance |
| Nitrógeno (norte) | 0.08–0.20% | Strength and stability |
| Carbón (do) | ≤0,03% | Reduces carbide formation |
| Manganeso (Minnesota) | ≤2.0% | Improves toughness |
Características clave de rendimiento de 2205 Hoja
1. Alta resistencia
2205 duplex stainless steel has approximately:
- 2× the strength of 304 acero inoxidable
This allows:
- Thinner material use
- Reduced structural weight
- Higher load-bearing capacity
2. Excelente resistencia a la corrosión
- Fuerte resistencia a ambientes clorados.
- High resistance to pitting and crevice corrosion
- Suitable for marine and chemical applications
3. Good Stress Corrosion Cracking Resistance
Compared to austenitic stainless steels:
- Much better resistance in chloride-rich environments
- Stable performance under stress and temperature variation
4. Balanced Duplex Microstructure
- ~50% austenite
- ~50% ferrite
This structure provides:
- Strength from ferrite
- Toughness from austenite
2205 vs 2507 Acero inoxidable dúplex
2507 (Super Duplex Stainless Steel) is the higher-grade version of 2205.
