UNS S32760 is a super duplex stainless steel grade selected for demanding chloride-bearing, marine and chemical-processing environments. A useful wire enquiry must define the specification, diameter, condition, surface, supply format and inspection requirements.
What Is UNS S32760?
S32760 combines a duplex microstructure with chromium, molybdenum, nitrogen, nickel, copper and tungsten alloying. This supports high strength and resistance to localized corrosion in suitable environments. Acceptance must follow the ordered specification and certified heat analysis.
Essential S32760 Wire Purchase Requirements
| Grade | UNS S32760 and any project specification |
|---|---|
| Diameter | Nominal size, tolerance and roundness |
| Condition | Solution-annealed, drawn or other specified condition |
| Supply format | Coil, spool, straight length, weight and internal diameter |
| Surface | Bright, clean, pickled or specified finish |
| Quantity | Total weight and permitted production tolerance |
Testing and Documentation
| Material certificate | Grade, heat or batch and reported results |
|---|---|
| Dimensional report | Diameter and agreed dimensional checks |
| PMI report | Alloy verification when specified |
| Optional testing | Corrosion, ferrite, NDT or third-party inspection when required |
| Packing list | Links coil or spool identification to shipment quantity |
Fabrication Considerations
Cold drawing changes strength, ductility and residual stress, so condition should match downstream forming or welding. Welding consumables and procedures must suit the joint and service. Finished wire should be protected from carbon-steel contamination and mechanical damage.
Typical Applications
Potential uses include marine and offshore components, chemical-processing equipment, chloride-service wire forms, screens, fasteners and fabricated assemblies. Suitability depends on chloride concentration, temperature, pressure, crevices and stress.
Common RFQ Mistakes
- Using super duplex wire without the UNS designation.
- Omitting diameter tolerance, condition or coil format.
- Requesting tests only after production.
- Assuming every S32760 product follows the same dimensional standard.
S32760 Wire RFQ Checklist
Send the UNS designation, standard, diameter and tolerance, condition, surface, coil or spool dimensions, quantity, tests, certificates, packing, destination and schedule.
