Product Description:
2205 Duplex Stainless Steel Sheets, also known as UNS S32205, are high-performance stainless steel products designed for superior strength, corrosion resistance, and durability. Combining the properties of both austenitic and ferritic stainless steels, these sheets are ideal for demanding industrial applications requiring high resistance to corrosion, especially in harsh environments.
Key Features of 2205 Duplex Stainless Steel Sheets
- High Strength: Offers approximately twice the yield strength of austenitic stainless steel grades like 304 and 316.
- Superior Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
- Durability: Exceptional toughness and ductility, even in cryogenic temperatures.
- Versatility: Suitable for environments exposed to chlorides, acidic, and alkaline conditions.
- Weldability: Easy to weld with standard methods while maintaining corrosion resistance properties.
