What are Super Duplex UNS S32760 Fittings?

UNS S32760 is a highly alloyed super duplex stainless steel known for its exceptional mechanical and corrosion-resistant properties. This grade features a dual-phase austenitic-ferritic microstructure combined with elevated chromium, molybdenum, tungsten, nitrogen, and copper content compared to standard duplex grades, giving it superior resistance to a wide range of corrosive attacks, including pitting, crevice corrosion, and chloride stress corrosion cracking.

UNS S32760 fittings are also commercially known as Zeron 100 fittings (a proprietary designation by Rolled Alloys), F55 fittings under the ASTM forging designation, and 1.4501 fittings under the European Werkstoff numbering system. These designations all refer to the same high-performance super duplex alloy. Procurement engineers and project specifiers frequently search under all of these names, so Solitaire Overseas supplies and certifies this material under all equivalent grade references.

Super Duplex S32760 fittings are characterized by:

Superior Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. With a Pitting Resistance Equivalent Number (PREN) exceeding 40, the high alloy content makes S32760 the preferred choice for environments where standard duplex steels would fail, including seawater piping, brine handling, and chloride-rich chemical service.
High Mechanical Strength: With tensile and yield strength significantly higher than standard austenitic stainless steels, these fittings are ideal for high-pressure and structural applications, enabling thinner wall sections and reduced system weight.
Excellent Weldability: The material is engineered for reliable welding with strict ferrite control and solution annealing, ensuring the integrity and longevity of the entire piping system.
Versatility: UNS S32760 fittings maintain their strength and ductility at both ambient and sub-zero temperatures, making them suitable for a wide variety of industrial applications from offshore platforms to cryogenic-adjacent services.

Zeron 100, F55, and 1.4501: Understanding S32760 Grade Designations

The grade UNS S32760 is the same alloy referred to by several international designations. Zeron 100 is the proprietary brand name originally developed by Rolled Alloys and is widely used in offshore oil and gas specifications. F55 is the ASTM forging designation under ASTM A182, while 1.4501 is the European EN / Werkstoff number. All three are equivalent to UNS S32760 and meet the same chemical and mechanical requirements. When selecting Zeron 100 fittings, F55 pipe fittings, or 1.4501 fittings for a project, Solitaire Overseas provides full cross-certified material test certificates confirming compliance with all applicable designations.

S32760 vs S32750: Key Differences in Super Duplex Fittings

Engineers frequently compare UNS S32760 and UNS S32750 (also known as 2507 or SAF 2507) when selecting super duplex fittings for aggressive service. Both grades share a similar base composition and a PREN value exceeding 40, which qualifies them both as super duplex stainless steels with outstanding pitting resistance. However, there are important differences that determine which grade is optimal for a given application.

S32760 (Zeron 100) contains 0.5 to 1.0% tungsten and 0.5 to 1.0% copper, which are not present in S32750. Tungsten improves resistance to pitting and crevice corrosion in reducing acid environments, while copper enhances resistance to sulfuric acid service and certain acidic chloride media. As a result, S32760 fittings are generally the preferred choice for mixed acid service, seawater injection systems, and highly aggressive chloride environments where S32750 may approach its corrosion limits. S32760 is, however, priced higher than S32750 due to the additional alloying elements. Where the application permits either grade, S32750 remains an economically competitive alternative.

Applications of Super Duplex S32760 Fittings

The robust mechanical and corrosion-resistant properties of UNS S32760 fittings make them the material of choice for critical piping systems in the most demanding industries.

Oil and Gas Industry: S32760 fittings are extensively used in offshore production platforms, subsea manifolds, HIPPS (High Integrity Pressure Protection Systems), topside piping, and riser systems. The combination of high mechanical strength and PREN greater than 40 meets the NACE MR0175 requirements for sour service environments. Forged S32760 elbows and tees are routinely specified for high-pressure wellhead connections and subsea tie-in spools where chloride-induced stress corrosion cracking would disqualify standard austenitic grades.
Desalination Plants: Reverse osmosis desalination plants place extreme demands on piping materials. S32760 fittings are widely used in high-velocity brine concentrate discharge lines, RO membrane headers, feed water distribution systems, and seawater intake piping. The resistance of Zeron 100 fittings to erosion-corrosion at elevated flow velocities makes them the preferred choice over standard duplex and austenitic grades in this application.
Chemical Processing Industry: In chemical plants handling hydrochloric acid (HCl), sulfuric acid, bleach production, phosphoric acid, and mixed acid streams, S32760 pipe fittings offer corrosion resistance far beyond 316L, 317L, or standard duplex S31803 grades. The tungsten and copper additions in Zeron 100 specifically enhance resistance to reducing acid environments, making F55 fittings the material of choice for bleach plants and mixed acid service headers.
Marine and Offshore Structures: S32760 fittings are used in seawater cooling systems, ballast piping, fire deluge systems, and hull piping on offshore vessels and FPSO units. Constant exposure to salt spray and oxygenated seawater requires materials with a PREN well above 40 to prevent pitting under crevice conditions. Marine propeller shaft couplings and adaptors manufactured from UNS S32760 also benefit from the grade's exceptional resistance to corrosion fatigue in seawater.
Chemical Tankers and Pulp and Paper Industry: Chemical tanker piping systems handling mixed cargo residues, acetic acid, and chlorinated solvents rely on S32760 fittings for their broad chemical compatibility. In the pulp and paper sector, S32760 buttweld fittings and forged fittings are used in bleaching chemical distribution, chlorine dioxide service, and white liquor handling systems where stainless steel grades with lower PREN values are prone to premature failure.

FAQ — Seamless Stainless Steel Pipe

What is UNS S32760 material?

UNS S32760 is a super duplex stainless steel alloy with a dual-phase austenitic-ferritic microstructure. It contains high levels of chromium (24 to 26%), molybdenum (3 to 5%), nitrogen (0.24 to 0.32%), tungsten (0.50 to 1.0%), and copper (0.50 to 1.0%), which together produce a PREN exceeding 40. It is commercially known as Zeron 100, F55, and 1.4501, and is widely used for piping fittings in offshore, desalination, and chemical processing applications.

What is the difference between S32760 and S32750 fittings?

Both S32760 and S32750 are super duplex stainless steels with a PREN greater than 40, but S32760 additionally contains tungsten (0.5 to 1.0%) and copper (0.5 to 1.0%), which are absent in S32750. These additions give S32760 enhanced resistance to reducing acids and aggressive seawater environments. S32760 is also slightly more expensive than S32750. For general corrosive service, both grades perform comparably; for mixed acid or seawater injection service, S32760 is typically preferred.

What is the PREN value of S32760 fittings?

The Pitting Resistance Equivalent Number (PREN) of UNS S32760 fittings exceeds 40. This is calculated using the formula PREN = Cr + 3.3(Mo + 0.5W) + 16N. The tungsten addition in S32760 contributes directly to the PREN calculation, further improving its resistance to pitting corrosion compared to grades without tungsten.

What are S32760 fittings used for?

S32760 fittings are used in offshore oil and gas platforms, subsea piping systems, seawater desalination plants, chemical processing units handling acids and chlorides, marine vessel piping, chemical tanker cargo lines, and pulp and paper industry bleaching systems. Any application requiring resistance to pitting, crevice corrosion, and chloride stress corrosion cracking in temperatures up to 300°C is a strong candidate for S32760 fittings.

Is S32760 the same as Zeron 100?

Yes. Zeron 100 is the proprietary brand name for the alloy designated UNS S32760. The same alloy is also designated F55 under ASTM A182 for forgings and 1.4501 under the European EN / Werkstoff system. Solitaire Overseas supplies S32760 fittings with dual or triple certification covering all of these designations on a single material test certificate.

What standards apply to ASTM A815 S32760 fittings?

Super duplex S32760 buttweld fittings are manufactured to the material standard ASTM A815 / ASME SA815. Dimensional standards applicable include ASME B16.9 (factory-made buttweld fittings), ASME B16.28 (short-radius elbows), and MSS SP-43. For forged fittings, the applicable material standard is ASTM A182 / ASME SA182 Grade F55. Additional compliance standards include NACE MR0175 / ISO 15156 for sour service and EN 10204 / 3.1B for material traceability.

What is the price of S32760 fittings?

The price of S32760 fittings depends on the fitting type (buttweld, forged, socket weld), size, wall schedule, quantity, and delivery requirements. As a super duplex grade with tungsten and copper additions, S32760 is priced higher than standard duplex S32750 or S31803 fittings.
