Applications & Uses of Super Duplex Steel S32760 Tube Fittings
Super Duplex UNS S32760 tube fittings are widely used across industries that demand exceptional corrosion resistance, high strength, and long-term reliability in aggressive environments. Their high PREN value (≥40) and enhanced alloy composition make them superior to conventional stainless steels like 316L and even standard duplex grades.
Below are key industries where super duplex stainless steel tube fittings are extensively applied:
- Offshore Oil & Gas:
S32760 tube fittings are standard in subsea control systems, topside instrumentation, and hydraulic lines on offshore platforms where chloride-induced corrosion and high operating pressures require a material exceeding the performance of 316L or standard duplex grades. - Chemical Processing:
The combination of Molybdenum (3–4%) along with Tungsten and Copper additions gives UNS S32760 material superior resistance to sulphuric acid, phosphoric acid, and mixed acid environments. Commonly used in heat exchanger tubing connections, reactor inlet/outlet systems, and chemical injection lines. - Desalination Plants:
With excellent resistance to chloride pitting and crevice corrosion, super duplex S32760 tube fittings are ideal for seawater reverse osmosis systems, including high-pressure tubing, brine manifolds, and membrane housing connections. - Marine & Shipbuilding:
Used in seawater cooling systems, ballast water treatment units, and saltwater hydraulic systems where constant exposure to chloride-rich environments demands materials beyond standard stainless steel capability. - Power Generation:
Applied in condenser tubing connections, cooling water systems, and flue gas desulphurisation (FGD) scrubber internals, where corrosion resistance at elevated temperatures is essential.

FAQs About Super Duplex Steel S32760 Tube Fittings
Super Duplex UNS S32760 is equivalent to EN 1.4501 and commonly referred to as F55 super duplex stainless steel.
S32750 (Super Duplex 2507) and UNS S32760 are both high-performance super duplex stainless steels, but they differ mainly in composition and corrosion resistance. S32760 includes additional alloying elements—Tungsten (0.5–1.0%) and Copper (0.5–1.0%)—which enhance resistance to reducing acids, particularly sulphuric acid and mixed chemical environments, whereas S32750 does not contain these additions. In terms of pitting resistance, both grades are strong, but S32760 typically offers a higher PREN value (≥40) compared to S32750 (~38–40), making it more suitable for highly aggressive chloride and acidic conditions. As a result, S32760 is preferred in demanding applications such as chemical processing and offshore systems requiring superior durability, while S32750 is widely used in general seawater and marine environments.
UNS S32760 is a super duplex stainless steel grade known for high strength, excellent corrosion resistance, and superior mechanical properties.
S32760 is similar to 2507 (UNS S32750) but includes added elements like tungsten, which enhance its corrosion resistance and durability in harsh conditions.
The PREN (Pitting Resistance Equivalent Number) of UNS S32760 is a minimum of 40, calculated as: PREN = Cr + 3.3(Mo + 0.5W) + 16N. This makes S32760 one of the most corrosion-resistant commercially available austenitic-ferritic stainless steel grades.
‘Condition S’ in S32760 refers to the solution-annealed and quenched condition as specified in ASTM A182 / EN 10216-5. The material is heat-treated at 1050–1150°C and rapidly quenched to achieve the balanced duplex microstructure required for optimal corrosion resistance and mechanical properties.
S32760 tube fittings are used in offshore oil platforms, chemical processing plants, desalination units, marine systems, and power generation applications where resistance to pitting, crevice corrosion, and stress corrosion cracking is critical.
