Duplex Stainless Steel Grades 2205 (UNS S31803/S32205) are highly regarded for their dual-phase microstructure, combining austenitic and ferritic properties. These tubes are designed for exceptional strength, superior corrosion resistance, and enhanced performance in challenging environments.
Key Features of Duplex 2205 (S31803/S32205) Tubes
- High Strength:
- Approximately double the yield strength of conventional austenitic stainless steels like 304 and 316.
- Exceptional Corrosion Resistance:
- High resistance to pitting and crevice corrosion in chloride-rich environments.
- Excellent stress corrosion cracking resistance.
- Durability and Toughness:
- Outstanding toughness even at sub-zero temperatures.
- High fatigue resistance in demanding applications.
- Cost-Effective:
- Reduced nickel and molybdenum content for cost efficiency without sacrificing quality.
- Environmental Sustainability:
- Lower environmental impact due to reduced alloying elements.
- High Strength:
