Buyer Decision Snapshot
Use this page when you already have drawings or a part concept and need to decide whether XHR is a fit for the process, material and inspection requirements.
What Buyers Usually Need
Why stainless is chosen
It is often used for parts that face moisture, chemicals, cleaning or wear.
What makes the quote harder
Grade choice, thread standards and finish requirements can all change machining time and inspection effort.
What should be marked
Threads, fits, sealing faces, diameter tolerance and cosmetic surfaces should be clear.
When to ask for certificates
Material certificates or inspection reports should be requested when the application needs them.
What to Send in the RFQ
- Current drawing revision and 3D model when available.
- Material grade, substitute options and any certificate requirement.
- Quantity, repeat quantity and target delivery date.
- Critical dimensions, threads, datums and surface finish notes.
- Inspection report, packing and shipping destination requirements.

Common Buyer Mistakes
Picking grade by habit
304, 316 and 17-4PH solve different problems and should not be used interchangeably.
Leaving threads vague
Thread standard, usable depth and gauge requirement should be explicit.
Ignoring passivation and finish
Corrosion and appearance requirements should be set before the order is priced.
How XHR Reviews This Order
Grade and machinability
XHR checks whether the selected stainless grade matches the function and the geometry.
Thread and fit control
The team reviews thread quality, diameter control and mating surfaces before quoting.
Inspection planning
Critical dimensions and finish expectations are separated from general geometry.
