A family name is not a specification
“Stainless steel” describes a broad family. Your enquiry should name the exact grade and the specification for the fitting product form.
Specify the grade.
Define the connection.
Explore the stainless steel grade families already listed in the Ferrobend catalogue, then define the fitting specification, dimensions and documentation your project requires.
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 |
|---|---|
| 304 / 304L | State the exact grade and whether dual certification is required. |
| 316 / 316L | Identify the specified grade rather than requesting only “marine grade”. |
| 321 | Use the full material specification and grade designation. |
| 347 | Include any project-specific heat-treatment or documentation requirements. |
Reference note: Outokumpu grade overview. Use the project’s approved specification for selection.

Drawing numbers, revisions and any project-specific notes.
COMMON QUESTIONS
Before you specify stainless steel
Are 304 and 304L interchangeable?
Do not assume that they are. Specify the grade required by the project. Any substitution or dual-certified material must be checked against the governing specification.
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.
