What Are Super Duplex Stainless Steel UNS S32760 Pipes?
Super Duplex Stainless Steel UNS S32760 Pipes are industrial pipes made from a high-alloy stainless steel grade designed for severe corrosive environments. This grade contains chromium, nickel, molybdenum, nitrogen and a small amount of copper and tungsten, which help improve strength and resistance to pitting, crevice corrosion and chloride stress corrosion cracking. Its balanced ferritic-austenitic structure allows the material to handle demanding service conditions where ordinary stainless steel may not provide sufficient performance.
These pipes are commonly used in offshore platforms, seawater systems, oil and gas processing, desalination plants and chemical industries. Their high mechanical strength and resistance to corrosion make them suitable for transporting fluids in environments exposed to seawater, chlorides and aggressive chemicals. The correct pipe dimensions and material specifications depend on operating pressure, temperature and the conditions of the application.

Standards and Project Requirements for Super Duplex Stainless Steel UNS S32760 Pipes
The main standard is ASTM A790 / ASME SA790, which covers both seamless and straight-seam welded pipe. Large fusion-welded pipe is covered by ASTM A928, general requirements come from ASTM A999, and pipe dimensions follow ASME B36.19M. European projects can reference EN 10216-5 and EN 10217-7 for grade 1.4501.
Many offshore and sour-service projects add their own layer, such as NORSOK or NACE MR0175 / ISO 15156. These set limits on hardness, ferrite and operating conditions. If your project calls for either, tell us at the enquiry stage so we can confirm what we can meet before you order.
Super Duplex Stainless Steel UNS S32760 vs S32750: Which One Do You Need?
These two are the most common pair in super duplex enquiries, and many drawings name one when either would do. Both reach a minimum yield of 550 MPa and similar pitting resistance. The difference is in how each gets there.
| Point | UNS S32760 | UNS S32750 |
|---|---|---|
| EN Number | 1.4501 | 1.4410 |
| Nitrogen | 0.20 – 0.30% | 0.24 – 0.32% |
| Molybdenum | 3.0 – 4.0% | 3.0 – 5.0% |
| Tungsten | 0.5 – 1.0% | None |
| Copper | 0.5 – 1.0% | 0.5% max |
| Tensile (min) | 750 MPa | 800 MPa |
| Yield (min) | 550 MPa | 550 MPa |
| Elongation (min) | 25% | 15% |
| Forged Form | ASTM A182 F55 | ASTM A182 F53 |
S32760 has higher guaranteed elongation, which gives it better ductility, and its tungsten and copper help in some acid and erosion-corrosion conditions. S32750 has a higher tensile minimum. For most seawater and chloride duty, either works. Check your specification before swapping, and ask us for dual-grade options if your drawing allows.

Mechanical and Physical Properties of Super Duplex Stainless Steel UNS S32760 Pipes
| Property | Requirement |
|---|---|
| Tensile Strength | 750 MPa (109 ksi) min |
| Yield Strength (0.2% offset) | 550 MPa (80 ksi) min |
| Elongation | 25% min |
| Hardness | 310 HBW / 32 HRC max |
| Density | approx. 7.8 g/cm³ |
| Elastic Modulus | approx. 200 GPa |
| Thermal Expansion (20–100 °C) | approx. 13.0 µm/m·°C |
| Thermal Conductivity (20 °C) | approx. 14 W/m·K |

Yield strength is about three times that of 316L. A pipe that carries the same pressure in a thinner wall saves weight and cuts support steel, which is a real benefit offshore.
Super Duplex Stainless Steel UNS S32760 Pipes Manufacturers and Suppliers in India
Manufacturing quality plays an important role in the strength and corrosion resistance of super duplex steel pipes. Controlled solution annealing, rapid cooling and proper testing help maintain the required material structure and mechanical properties. Our focus on these processes supports the supply of Super Duplex Stainless Steel UNS S32760 Pipes for demanding industrial applications.
As a Super Duplex Stainless Steel UNS S32760 Pipes Supplier in India, we provide material documentation and inspection support according to project requirements. Available checks may include chemical composition analysis, hardness testing, ferrite content measurement, positive material identification (PMI) and heat treatment records. We also supply related piping products, including ASTM A182 F55 flanges, ASTM A815 fittings and ASTM A240 plates, subject to grade availability and applicable standards. These options help meet the material and documentation needs of oil and gas, offshore, marine and chemical processing projects.
Seawater, Erosion and Temperature Performance of Super Duplex Stainless Steel UNS S32760 Pipes
In seawater and hot chloride brine, S32760 resists pitting and crevice corrosion far better than 316L or 2205. Its critical pitting temperature in ASTM G48 testing typically lands in the same range as S32750, roughly 70–85 °C, compared with about 35 °C for 2205.
The grade is popular where the fluid carries sand or solids. High strength and hardness help the pipe wall resist erosion-corrosion, which is the combined damage of flow and chemistry. The copper addition also gives some extra resistance in non-oxidizing acids, which matters in scrubber and chemical lines.
Its limit is heat. Most designs keep super duplex below about 250 °C, and codes list stress values only to roughly 315 °C. Long exposure between about 300 and 525 °C embrittles the ferrite, and above about 600 °C brittle sigma phase forms. That rules S32760 out for steam and furnace service, where P91, P92 or 347H are the right picks.
Welding and Heat Treatment of Super Duplex Stainless Steel UNS S32760 Pipes
Welding super duplex means holding the balance between ferrite and austenite. A matching filler such as ER2594 is normal, because welding without filler can leave too much ferrite. Heat input is usually kept to roughly 0.5–1.5 kJ/mm, interpass temperature under about 100 °C, and post-weld heat treatment is normally avoided.
At the mill, pipe is solution annealed at about 1010–1100 °C and quenched fast. That fast quench traps the two-phase structure and stops brittle phases from forming. After welding, pickling and passivation restore the surface. Check ferrite against your project range, commonly about 35–55% in the base metal. Always follow a qualified welding procedure.
Super Duplex Stainless Steel UNS S32760 Pipes Size and Weight Chart
Weight per metre = (OD − wall) × wall × 0.0245, with OD and wall in mm. This assumes a density of about 7.8 g/cm³. Treat the results as estimates, since wall tolerance moves the actual weight.
OD and wall are in mm. Multiply the result by the pipe length to obtain the total weight.
| NPS | OD (mm) | Sch 10S Wall | kg/m | Sch 40S Wall | kg/m | Sch 80S Wall | kg/m |
|---|---|---|---|---|---|---|---|
| ¾" | 26.7 | 2.11 | 1.27 | 2.87 | 1.68 | 3.91 | 2.18 |
| 1½" | 48.3 | 2.77 | 3.09 | 3.68 | 4.02 | 5.08 | 5.38 |
| 2" | 60.3 | 2.77 | 3.90 | 3.91 | 5.40 | 5.54 | 7.43 |
| 4" | 114.3 | 3.05 | 8.31 | 6.02 | 15.97 | 8.56 | 22.18 |
| 8" | 219.1 | 3.76 | 19.84 | 8.18 | 42.27 | 12.70 | 64.22 |
| 10" | 273.1 | 4.19 | 27.60 | 9.27 | 59.92 | 12.70 | 81.03 |
A quick example: a 4" Sch 40S pipe weighs (114.3 − 6.02) × 6.02 × 0.0245 = 15.97 kg/m, so a 6 m length weighs about 96 kg. For any other size, we can send a full chart on request.
