For Vendors Selling to Stainless Machine Shops
Bar and plate, carbide tooling, passivation, heat treat, inspection and freight. We name vendors in our guides where the technical context calls for it. Placement is not for sale.
The shops reading this site quote medical, food, pharma and marine work. What decides their supplier is not the catalogue, it is whether the certificate satisfies an auditor and whether the material is on the shelf this week.
If you certify to a spec, name the spec. That is the part a shop cannot get from a brochure.
What a stainless shop buys, and what decides it
Five groups. A shop quoting 316L with a Ra 0.8 callout and a passivation certificate is making decisions in all five before it prices the job.
- Bar, plate and tubeCut to size in 303, 304L, 316L, 17-4 PH, 416 and 2205, with mill certs carrying the heat number. Medical and food buyers trace the material back to the melt, so a missing cert stops the job. What a shop weighs: what you hold in the region, cut charges, and whether an odd section means a six week wait.
- Carbide tooling and insertsGrades and geometries made for austenitic stainless: sharp edges, positive rake, coatings that survive the heat. A worn edge work hardens the surface and the next pass pays for it. What a shop weighs: stock on the shelf, regrind turnaround, and whether an engineer will look at a galling problem on the floor.
- Passivation and electropolishingCitric and nitric passivation to ASTM A967, cleaning to ASTM A380, electropolishing to ASTM B912, with certificates that name the process and the batch. What a shop weighs: turnaround, whether the certificate satisfies a medical or food auditor, and minimum lot charges on small batches.
- Heat treat and markingSolution anneal and age hardening for the PH grades including H900 and H1150, plus laser marking that does not wreck the passive layer. What a shop weighs: furnace records it can show a customer, hardness testing, and whether marking is done before or after passivation.
- Inspection, packing and freightOutsourced CMM, surface roughness measurement, cleanroom bagging and forwarders used to medical and food equipment parts. What a shop weighs: report formats an auditor accepts, documented cleanliness levels, and someone who answers when a shipment is held.
How a vendor gets named
Four tests, applied the same way every time. They are about the shop reading the guide, not about you.
- The guide has to be about your problemA tooling vendor belongs in a piece about work hardening, not in one about lead times.
- The detail has to be checkableWhere stock sits, real lead time, which spec you certify to. We write what we can verify.
- You have to reach these shopsYou supply shops that cut stainless, or you deliver to them inside a lead time they will accept.
- Named once, never rankedOne mention per guide, no ordering, and no claim we cannot stand behind.
What we do not sell
- PlacementNo sponsored slot, no position, no advertorial dressed as a guide.
- RankingWe do not order vendors by budget. A shop reading a ranked list learns nothing from it.
- Unverified claimsIf we cannot check a lead time or a specification, it does not go on the page.
- Shop contact listsShop details stay with us. That is the deal we made with the shops.

Questions vendors ask
Can I pay to be listed or ranked?
No. Placement is not sold and there is no paid ranking. A vendor is named in a guide only where the technical context calls for it.
What do you want from a vendor?
Specifics: what you hold in stock and where, real lead times from that stock, the spec you certify to, and what you cannot supply. That is what makes a mention useful to the shop reading it rather than an advert.
Will you send me the shop list?
No. We do not sell or share contact lists. Where an introduction genuinely helps a shop we ask the shop first.
How often are guides updated?
When something changes that affects the advice, for example a lead time, a grade being discontinued, or a certificate a buyer now demands.
