Product Description:
2205 Duplex Stainless Steel Plates, also known as UNS S32205, are high-performance, corrosion-resistant plates combining the best qualities of austenitic and ferritic stainless steels. These plates are designed for applications requiring high strength, excellent corrosion resistance, and durability in challenging environments.
Key Features of 2205 Duplex Stainless Steel Plates
- High Strength: Offers twice the yield strength of standard austenitic stainless steel like 304 and 316.
- Exceptional Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich environments.
- Cost-Effective: Combines high performance with lower alloying costs compared to austenitic stainless steels.
- Durability: Outstanding toughness and resistance to mechanical wear, even at cryogenic temperatures.
- Environmentally Friendly: Lower alloy content makes it a sustainable choice for industrial applications.
