Avoid incomplete designations
Include the specification, grade and any required class. A short grade label may omit information needed to define the material.
The right designation.
A controlled requirement.
Alloy steel fittings need an exact grade and supply specification. Explore the catalogue grade references and identify processing, testing and documentation requirements for review.
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 |
|---|---|
| WP5 / WP9 | Identify the full specification and the exact requested grade. |
| WP11 | Include the class or other supplementary designation when required. |
| WP22 | Provide the complete project material designation and supply condition. |
| Other alloy grades | Supply the relevant specification for technical review. |
SPECIFICATION DETAILS
Make the material requirement clear
Keep material identity and acceptance criteria together.
Include the project supply requirements
Heat-treatment, welding and inspection requirements should be taken from the applicable specification and agreed supply scope.

- Fitting configuration
Product type, sizes, wall thicknesses and applicable dimensional standard.
- Project conditions
Relevant service information and the approved material specification.
- Supply & inspection
Manufacturing condition, tests, certificates and marking requirements.
- Quantity & destination
Item quantities, required date and delivery location.
- Drawing references
Drawing numbers, revisions and any project-specific notes.
COMMON QUESTIONS
Before you specify alloy steel
Can WP5, WP9, WP11 and WP22 be substituted?
Do not treat these grade references as interchangeable. Any proposed substitute must be reviewed against the project material 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.
