Product Description:
Duplex Stainless Steel Grades 2205 (UNS S31803/S32205) are highly versatile materials offering exceptional mechanical properties and corrosion resistance. These pipes and fittings are ideal for use in industries requiring superior strength, durability, and performance in corrosive environments.
Key Features of Duplex Stainless Steel 2205 (S31803/S32205) Pipes and Fittings
- High Strength: Twice the yield strength of conventional austenitic stainless steels like 304 and 316.
- Superior Corrosion Resistance:
- High resistance to pitting and crevice corrosion in chloride-rich environments.
- Excellent resistance to stress corrosion cracking and general corrosion.
- Enhanced Durability:
- Outstanding toughness, even at low temperatures.
- Excellent fatigue resistance.
- Cost Efficiency:
- Lower alloying costs due to reduced nickel and molybdenum content.
- Environmental Sustainability:
- Reduced environmental impact during production.
