Put these on the RFQ for Stamped Part before you compare prices.

A buyer searching for Stamped Part is usually trying to stop a bad substitute. A metal product is specified by alloy, temper or grade, dimensions, and the certificate. The notes below are selection criteria for a Stamped Part. They are not a catalog promise. Confirm every rating on the current datasheet, drawing, or test report for the revision you will receive.

What has to be true of Stamped Part

A metal product is specified by alloy, temper or grade, dimensions, and the certificate. For a Stamped Part, start from the duty, then the interface to the rest of the machine or the room, then the document that proves the claim. A lower price that leaves one of those blank is a different product.

Stamped Part is easy to confuse with Metal Door Frame. If the quote could be read as either, add the line that separates them: the rating, the fitment, or the standard named below. Link the drawing number to that line so receiving inspection can reject the wrong one.

Numbers that change the quote

Line What to write for Stamped Part
Quantity Weight or pieces, and the bundle.
Alloy The grade designation, not only steel or aluminum.
Temper or condition Temper, hardness, or heat-treat condition.
Dimensions Thickness, width, length, and tolerance.
Surface Mill finish, coated, or a stated roughness.
Certificate A mill certificate of the type the job requires, such as an EN 10204 type if that is what you need.

How to compare two offers

Lay both quotes for Stamped Part on one sheet and line up quantity, alloy, and temper or condition. If a cell is empty, the offer is not finished. Ask for the missing line in writing. When those match, the honest difference is lead time, the test evidence, and who carries the warranty. Do not average a fully specified Stamped Part with a cheaper line that omitted quantity.

Documents worth having before the deposit

Ask for the certificate type with the grade. The file should name Stamped Part and the revision, not only the supplier’s homepage. A factory quality certificate such as ISO 9001 can sit beside that file. It does not replace it.

Failures that show up after delivery

  • Accepting a trader’s stamp in place of a mill certificate.
  • Ordering stainless without the alloy.
  • Leaving temper off a sheet that will be formed.

On a Stamped Part, the expensive version of the first mistake is discovering it after the goods are in the crate. Put the rejection condition in the purchase order while the supplier can still restate the offer.

A worked RFQ line

Use this shape, then replace the brackets with your duty: “Stamped Part — State alloy, temper, dimensions, surface, and certificate type.” That sentence is a template, not a rating of any brand. If a supplier’s datasheet uses different units, convert them onto this sheet so the next offer can be compared.

Where words like outdoor belong

Searches often add a constraint to Stamped Part: outdoor, or RoHS / CE. Keep those on this page. Outdoor means UV, temperature cycle, and corrosion, not only a gasket. Name the climate and the years the gasket is expected to last. RoHS is a material limit. CE is a declaration that lists the rules relied on. Ask for the document that names this part number and revision. If you need a third constraint, add it as another line on the same drawing. A second URL that only swaps the adjective does not give a buyer a second fact.

Questions buyers actually ask

What should an RFQ for Stamped Part include?

State alloy, temper, dimensions, surface, and certificate type.

Is a cheaper Stamped Part the same part?

Only if quantity, alloy, and the documents match. A missing line is a different offer.

Do waterproof, OEM, or IP words need their own page?

No. For Stamped Part they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
