Name the material.
Define the supply.
A family name is a starting point. An enquiry should identify the product specification, grade, supply condition and documentation.
Material requirements
A practical checklist—not a substitute for the applicable standard.
| Requirement | What to include |
|---|---|
| Specification | Applicable material specification and edition for the fitting product form. |
| Grade | Complete grade designation and any required class or supplementary requirements. |
| Supply condition | Required manufacturing route, heat treatment and delivery condition where applicable. |
| Traceability | Marking, material identification and document requirements. |
| Project requirements | Service conditions and any project-specific testing or acceptance requirements. |
Make the requirement clear.
- Product form
A pipe or plate specification does not automatically define a finished fitting.
- Alternatives
Do not substitute grades without documented project approval.
- Documentation
Agree certificates and inspection records before placing the order.
- Availability
Confirm the requested grade, geometry and supply condition together.

Is the grade name enough for an enquiry?
Include the applicable product specification, grade, dimensions, quantity and any supplementary requirements.
Are similar grades interchangeable?
Not automatically. Any alternative requires review against the project requirements and approval.
Can I request inspection certificates?
State the required document type and traceability scope in the enquiry so these can be reviewed before ordering.
Are material and dimensional standards separate?
They address different requirements. A complete specification may need both, together with the project requirements.
Bring the details together.
