Short answer: A useful stainless steel RFQ identifies the grade and standard, product form, full dimensions, quantity, finish, edge, tolerance, protective film, packing, certificate, destination and application. Missing fields force suppliers to assume and make quotations difficult to compare.
This guide is written for stainless steel buyers, sourcing teams, engineers and product manufacturers. The purpose is not to declare one universal winner, but to turn a broad material question into a specification that a mill or service center can quote, process and inspect consistently.
Quick Comparison
| Option | Key point | Typical use or decision |
|---|---|---|
| Material | Grade, UNS/EN/JIS designation and standard | Prevents unintended substitution |
| Dimensions | Thickness, width, length or coil weight/ID | Defines processing route |
| Surface | 2B, BA, brushed, mirror and film | Controls appearance |
| Quality | Tolerance, edge, flatness, MTC and tests | Creates measurable acceptance |
| Logistics | Quantity, packing, port and delivery date | Makes landed planning possible |
The table is a starting point. Actual performance depends on the governing standard, delivered condition, dimensions, surface finish, fabrication route and service environment. Commercial names should never replace a complete purchase specification.
What Buyers Should Evaluate
- Attach a drawing for finished blanks or tight tolerances.
- Describe the end use so the supplier can flag an unsuitable grade or finish.
- Separate mandatory requirements from preferences.
For production orders, share the end use rather than requesting a grade or finish in isolation. A supplier can then review corrosion exposure, forming severity, welding, visual requirements and packing before material is cut. This early review is usually less expensive than correcting a rejected shipment or unstable production trial.
Common Purchasing Mistakes
- Writing only ‘304 coil, best price’
- Omitting whether width means master coil or slit strip
- Requesting food grade without naming the target market or standard
These mistakes are avoidable when drawings, approved samples, inspection methods and certificate requirements are agreed before production. For visual products, retain a signed master sample. For functional dimensions, define where and how measurements will be taken.
Recommended RFQ Wording
Use this line: Grade / standard; form; thickness × width × length or coil weight; finish; edge; tolerance; film; quantity; MTC; packing; destination; required date; end use.
Also include order quantity, acceptable quantity variation, destination, required delivery date and whether partial shipments are allowed. If a requirement is critical, make it measurable and place it on the purchase order rather than only in an email conversation.
How Still Steel Supports the Project
Still Steel supplies stainless steel coil, strip and sheet and provides slitting, cut-to-length, brushing, polishing and protective-film services. We can compare available mill material with your drawing, prepare trial quantities and preserve heat-number traceability through service-center processing.
Send the grade, dimensions, annual volume and application to vip@still-steel.com, or discuss the requirement on WhatsApp.
Frequently Asked Questions
Why does the supplier ask about end use?
Application details help identify corrosion, forming, finish and certification risks before production.
Should an RFQ include tolerance?
Yes, especially when components depend on minimum thickness, slit width, flatness or burr limits.
What certificate should be requested?
Many industrial buyers request an EN 10204 3.1 inspection certificate, subject to the governing product specification.
