2205 and 2507 duplex stainless steel strips are high-performance materials with a dual-phase microstructure (austenite + ferrite), offering outstanding strength and excellent corrosion resistance.
Compared with standard austenitic grades like 304 and 316, duplex stainless steels provide higher mechanical strength, superior chloride resistance, and better stress corrosion cracking resistance, making them ideal for demanding environments.
- 2205 (UNS S31803 / S32205): Standard duplex grade with balanced strength and corrosion resistance
- 2507 (UNS S32750): Super duplex grade with enhanced pitting resistance and extreme durability
