At Stephens Gaskets, we manufacture and supply UNS S32760 super duplex washers for industries that demand uncompromising strength and corrosion resistance.
Designed to perform in the world’s most aggressive environments, these washers are built to endure where standard materials fail.
As a trusted UNS S32760 super duplex washers company in the UK, we help clients in offshore, chemical, marine, and energy sectors ensure long-term safety and reliability.

What Are UNS S32760 Super Duplex Washers?

UNS S32760 super duplex washers are heavy-duty load distribution components made from a high-alloy grade of stainless steel.

This material combines the properties of both austenitic and ferritic steels, delivering high tensile strength alongside exceptional resistance to corrosion, pitting, and fatigue.

Commonly known by the trade name Zeron 100®, UNS S32760 contains elevated levels of chromium, molybdenum, and nitrogen.

These washers are designed for use in harsh, chloride-rich, and high-pressure environments, where failure is not an option.

Why Choose UNS S32760 for Washers?

These washers are not ordinary stainless fasteners. They are engineered for severe service conditions.

  • Exceptional Corrosion Resistance: Especially in seawater, brine, and oxidising chemical environments.
  • High Mechanical Strength: Roughly double the strength of conventional 316 stainless.
  • Fatigue and Impact Resistant: Suitable for systems with pressure cycling, vibration, or mechanical shock.
  • Long-Term Performance: Reduces the need for frequent replacements or shutdowns.
  • Temperature Stability: Maintains integrity in both elevated and fluctuating temperatures.
These advantages make UNS S32760 washers the go-to choice for critical fastening where safety and uptime matter most.

Key Benefits of UNS S32760 Super Duplex Washers

1. Superior Corrosion Resistance

Outperforms 316L, 904L, and even many other duplex grades. Offers exceptional resistance to pitting, crevice corrosion, and chloride-induced stress cracking.

2. High Load-Bearing Capacity

Its yield strength is nearly twice that of standard stainless steels, enabling it to withstand extreme loads and clamping forces without distortion.

3. Long-Term Durability

Reduces maintenance and replacement cycles, especially in remote or difficult-to-access installations.

4. Excellent Performance Under Pressure

Maintains tight joints in dynamic systems and high-vibration applications, helping to prevent loosening over time.

5. Thermal and Mechanical Stability

Performs reliably under fluctuating temperatures and continuous mechanical stress, making it ideal for rotating equipment and structural anchors.

6. Precision Engineering and Customisation

Available in various formats, including flat washers, shim washers, and spring washers. Manufactured to British, DIN, ISO, or custom standards.

Applications of UNS S32760 Super Duplex Washers

UNS S32760 washers are relied upon in sectors where environmental stress and mechanical loading are constant.
Their key applications include:

1. Offshore and Marine Engineering
Used in flanges, valves, and bolted joints in underwater and dockside infrastructure. Their corrosion resistance ensures long service life in seawater and brine environments.
2. Oil and Gas Industry
Common in subsea systems, refineries, heat exchangers, and compressor units. These washers support high-pressure and high-temperature sealing in both upstream and downstream operations.
3. Chemical and Petrochemical Processing
Installed in reactors, storage tanks, and pipe systems where exposure to aggressive chemicals is frequent.
4. Desalination and Water Treatment
Used in high-pressure reverse osmosis systems, brine lines, and pump housings. Performs well in saline conditions where other grades corrode.
5. Pulp and Paper Mills
Supports mechanical and thermal loads in bleach plants, digesters, and evaporators where chloride-based chemicals are present.
6. Power Generation
Withstands high-temperature cycling in steam and water pipelines in nuclear, hydro, and thermal power plants.
7. Infrastructure in Aggressive Environments
Used in fasteners for bridges, tunnels, and coastal structures where airborne salts and pollutants are prevalent.
8. Aerospace and Defence
Deployed in bolted joints for equipment exposed to both high stress and environmental corrosion. Selected for its combination of strength and lightness.

Material Comparisons and Industry Use

Material Grade Corrosion Resistance Strength Ideal Use Case
316L Stainless Moderate Low General industrial
Duplex 2205 Good Medium Structural and low-chloride environments
UNS S32760 Excellent High High-pressure, chloride-rich settings
Inconel 625/718 Excellent High High-temp and sour service
Monel 400 Good Moderate Sour gas and marine
UNS S32760 stands out due to its combination of strength, corrosion resistance, and longevity.

FAQs About UNS S32760 Super Duplex Washers

What is UNS S32760 made of?
It’s a super duplex stainless steel alloyed with chromium, molybdenum, tungsten, and nitrogen to maximise corrosion and mechanical resistance.
Is it better than 316 or 2205?
Yes. It offers superior strength and corrosion resistance in aggressive environments where 316 and 2205 may degrade over time.
Where is it used most?
It’s used across oil and gas, desalination, marine, power generation, and chemical processing industries.
Can you supply custom sizes?
Yes. We offer flat, shim, and spring washers in standard and non-standard sizes with tight tolerances.
What finishes are available?
We can supply washers as-machined or with coatings such as passivation, pickling, or black oxide depending on application.
Do you offer material certification?
Yes. All washers are supplied with EN 10204 3.1 certification and traceability to heat and batch records.
What are typical lead times?
Standard sizes are often available from stock. Custom sizes are manufactured promptly with fast turnaround.
