Material to UNS S32750 (Duplex 2507 / 1.4410 / F53) is described as a super duplex stainless steel with a microstructure of 50:50 austenite and ferrite. UNS S32750 Duplex steel combines high mechanical strength (typically up to 570 MPa yield strength) and good ductility with outstanding corrosion resistance in marine environments. The alloy is supplied with a PREN (Pitting Resistance Equivalent) at ≥40.0 which guarantees high resistance to pitting corrosion. In addition, the steel offers high resistance to crevice corrosion and stress corrosion cracking. Ambient and sub-zero (down to minus 50°C) notch ductility is good. ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering Duplex 2507 UNS S32750 at factory-direct prices with full material traceability and fast global delivery.

Fabrication & WeldabilityHeat Treatment: Solution anneal at 1025-1125°C (1877-2057°F), water quench — essential to maintain phase balance Welding: Good weldability with controlled heat input; matching super duplex filler metals (2507/P100) required to maintain corrosion resistance Forming: Higher strength requires more powerful equipment than austenitic grades; good cold formability with proper allowances Machining: Higher cutting forces than standard duplex; requires rigid setups, sharp tools, and adequate coolant
ApplicationsCommercial applications for this engineering material include: - Pumps, valves, chokes
- Pipework/flanges
- Connectors
- Manifolds
- Oil & gas components
