Keep the grade distinction clear
S32750 and S32760 should be named individually in the enquiry. A broad family description is not an instruction to substitute grades.
Specific grades.
Clearly defined requirements.
Explore super duplex fitting enquiries using the exact UNS grade and project specification. Material identification, processing and inspection requirements belong in the same scope.
GRADE OVERVIEW
Start with the complete designation
The grade references below help structure an enquiry. They are not a statement of stock, equivalence or suitability for a particular service.
| Grade / detail | What to specify |
|---|---|
| UNS S32750 | Include the full fitting specification and requested grade. |
| UNS S32760 | State this grade explicitly rather than requesting “super duplex” alone. |
| Inspection requirements | Identify project-specific tests and acceptance criteria before quotation. |
Reference note: Outokumpu duplex and super duplex guide. Use the project’s approved specification for selection.
SPECIFICATION DETAILS
Make the material requirement clear
Keep material identity and acceptance criteria together.
Connect the material to its documents
Define marking and certificate requirements so the delivered fitting and its material documentation can be identified together.

Item quantities, required date and delivery location.
- Drawing references
Drawing numbers, revisions and any project-specific notes.
COMMON QUESTIONS
Before you specify super duplex
Can I request any super duplex grade as an alternative?
List only the alternatives approved by your project specification. Grade changes need technical review and should be agreed before supply.
Does this page confirm stock or delivery time?
No. Availability and delivery depend on the exact fitting, grade, dimensions, quantity and documentation requirements. These must be confirmed in the quotation.
Which fitting sizes are available in this material?
Send the required fitting type, end sizes and wall thicknesses. Availability is reviewed for that combination; a material family does not define a universal size range.
What certificates should I request?
Specify the certificate type, material traceability, inspection and testing required by the project. Include supplementary requirements with the initial enquiry.
