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.
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.
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:
Material Comparisons and Industry Use
| Material Grade | Corrosion Resistance | Strength | Ideal Use Case |
