18/10 vs 18/0 Stainless Steel Cutlery: What Hotels Should Specify

Short answer: for hotel and restaurant use, specify 18/10. The "18" is chromium and the "10" is nickel. 18/0 has chromium but effectively no nickel, so it costs less and corrodes sooner under commercial dishwashing. 18/10 costs more per piece and lasts through years of daily wash cycles — which is why almost every hotel group we supply runs 18/10 in their main dining rooms.

The rest of this page is about the cases where that simple answer needs adjusting.

What the numbers actually mean

Stainless steel is named by its two main alloying elements.

	18/10	18/0
Chromium	18%	18%
Nickel	10%	<1% (usually none)
Crystal structure	Austenitic	Ferritic
Magnetic	No	Yes
Looks	Warm, deep shine	Brighter, slightly harder white
Corrosion resistance	High	Moderate to low
Typical cost index	100	55–70
Typical use	Hotels, restaurants, banqueting	Cafés, canteens, catering disposables, retail sets

Nickel is what makes the steel austenitic. That single change is why 18/10 holds a polish, resists pitting from chlorides and dishwasher detergents, and can be re-polished rather than replaced.

The three things that actually fail in service

Buyers usually compare cutlery on price per dozen. In practice, three failure modes decide the total cost:

1. Pitting on 18/0 in commercial dishwashers. Commercial machines run hotter water, stronger detergent and shorter cycles than domestic ones. Chlorides in detergent attack the passive chromium layer, and low-nickel steel has less capacity to rebuild it. Result: small dark pits on the bowl of the spoon or the flat of the blade — usually visible within the first year in a busy operation.

2. Loss of shine before loss of function. A mirror-polished 18/0 fork will still be structurally fine while looking dull and grey. In a guest-facing dining room that reads as "tired" long before it reads as "broken". This is the most common reason hotels replace flatware that isn't actually worn out.

3. Bent tines and handles. This is a thickness and geometry problem, not a nickel problem. See our flatware weight guide — a thin 18/10 fork will bend before a thick 18/0 one.

If you need a documented comparison, we can run the same salt-spray protocol on 18/10 and 18/0 from the same production line and report the pitting onset for both. Tender documents often require the test report attached — ask for it when you request a quote.

When 18/0 is the right answer

18/0 is not a bad material. It is the right material when:

• The setting is self-service or back-of-house — staff canteens, buffet pick-up, catering where loss and breakage dominate the cost model
• Volume is very high and replacement is expected — festival catering, one-off events, temporary outlets
• The pieces are decorative rather than handled — display, showroom, staging
• Budget is the binding constraint and the venue is dry — a venue that hand-washes and dries promptly will get years out of 18/0

What we do not recommend is mixing the two in one dining room. Once 18/10 and 18/0 sit in the same drawer, staff cannot tell them apart and the 18/0 pieces drag the perceived quality of the whole set down.

How to specify it so the quote matches the product

If you are writing a purchase specification or a tender document, these are the lines that matter:

Material: 18/10 stainless steel (AISI 304), nickel content ≥ 8%
Thickness: ___ mm at the tine root and bowl — get this figure from the supplier, it rarely appears on a quotation
Finish: mirror polished **or** satin brushed — name one, not "stainless"
Corrosion: request the salt-spray report and the wash-cycle protocol the supplier tests to
Marking: laser-etched logo, underside of handle
Packaging: pieces per dozen, per inner box, per master carton — confirmed on the PI

Two of these are frequently missing from tender documents and cause most of the disputes afterwards: nickel content (some suppliers quote "18/10" for steel that tests below 8% nickel) and thickness at the working end (a 2.0 mm fork and a 3.0 mm fork are both "18/10").

Ask for the mill certificate. A supplier who cannot produce one is not selling 18/10.

What we supply

Every cutlery series we make is 18/10 stainless steel in a mirror polish, from the Apollo and Pearl ranges through to the General workhorse line used in staff dining and banqueting. We also produce 18/0 on request for back-of-house programmes.

We do not publish a standard minimum order quantity for flatware — quantities are quoted per project, and we will price a 200-piece trial order the same way we price a 20,000-piece rollout.

FAQ

Is 18/10 cutlery magnetic?

No. Austenitic 18/10 is non-magnetic. If a magnet sticks firmly to a piece sold as 18/10, it is either 18/0 or a lower grade — this is the fastest field test available to a buyer.

Can you tell 18/10 from 18/0 by looking at it?

Not reliably on new stock. Over 12–24 months of dishwashing the difference becomes obvious: 18/0 dulls and pits, 18/10 keeps its surface. Weight is also a weak signal, because thickness varies independently of grade.

Is 18/10 dishwasher safe?

Yes, in both domestic and commercial machines, provided the detergent is not excessively chloride-based and pieces are not left wet in a closed drawer. Where a tender requires a cycle figure, we test to the protocol agreed with the client and supply the report.

What is 18/8 — is it different from 18/10?

18/8 is the same austenitic family with slightly less nickel; in practice the grades overlap and many mills use them interchangeably. If a specification matters to you, specify nickel content as a minimum rather than a nominal grade name.

Does a higher nickel content make the fork stronger?

No. Nickel drives corrosion resistance and shine retention. Bend strength comes from thickness and geometry — that is a separate specification, covered in the weight guide.

What does upgrading from 18/0 to 18/10 cost?

More than the metal alone suggests: 18/10 carries nickel, which is the expensive alloying element, where 18/0 carries almost none. The exact premium is quoted per order because it moves with alloy pricing. Against a two-to-three-year replacement cycle for 18/0 in a busy dining room, the 18/10 line usually costs less per year of service.
