304 vs 201 vs 430 Stainless Steel: Which Grade for Cookware Export?

The short answer

For retail cookware that will be used daily and washed frequently, 304 is the safe specification and 201 is the cost-reduced alternative that most of the market actually buys. For buffet, serving and display ware where the item touches food briefly and is not exposed to strong acids or chlorides, 430 is adequate and materially cheaper. For cleaning hardware, scoops and shovels, 410 is the correct choice because hardness and abrasion resistance matter more than corrosion resistance, and food contact is not the use case.

If you want one rule: choose by what the article touches and how often it is washed, not by which number sounds more premium. The practical test is a short sequence of questions. Does the article hold food for a long period, or hold salt or acid? Then specify 304. Does it touch food briefly, at ambient temperature, and get washed by hand? Then 430 is defensible. Does it never touch food at all, but scrape or abrade a hard surface? Then 410 is better than any of the food grades, and cheaper. Everything else — gift sets, open-stock saucepans sold through grocery — usually lands on 201, priced to the channel it is sold into.

What the grade number actually describes

The three-digit designation describes a family of alloys, not a quality ranking. What changes between families is the balance of chromium, nickel and — for 201 — manganese. Chromium produces the passive oxide layer that makes the steel stainless at all. Nickel stabilises the austenitic crystal structure, which is what gives 304 its formability and its resistance to chloride attack. Manganese can substitute for part of the nickel to hold the austenitic structure at lower cost, which is the entire economic logic of 201.

Austenitic 201 and 304

304 is the reference grade: roughly 18% chromium and 8% nickel, which is why it is often written 18/8. It is austenitic, non-magnetic in the annealed state, highly formable, and tolerant of the acids and salts found in food. 201 keeps a similar chromium level but cuts nickel to roughly half or less and adds 5.5–7.5% manganese plus nitrogen to preserve the austenitic structure. It is also non-magnetic, also formable, and visibly indistinguishable from 304 on a shelf. In our range, 201 accounts for 95 of 241 models and 304 for 35, which reflects how the wholesale market actually buys: 201 for volume retail programmes, 304 where the buyer's specification or retailer requirement names it.

Ferritic 430

430 carries 16–18% chromium and essentially no nickel. That makes it the cheapest of the three, but it is ferritic rather than austenitic, which has two consequences a buyer must plan for: it is magnetic, and its corrosion margin in chloride conditions is narrower than 304. It forms and welds well and takes a polish readily, which is why it is common in trays, buffet pans, splash zones and decorative trim. We produce 18 models in 430, mainly in the serving and tray group. It is a legitimate material — it is simply not the material to specify for a saucepan that will hold salted stock for an hour.

Where 410 fits

410 is a martensitic grade with roughly 11.5–13.5% chromium and no nickel. It is magnetic, hard, and takes abrasion far better than 304, but its corrosion resistance is the lowest of the group. That combination makes it right for dustpans, scoops, shovels, scrapers and broom fittings, where the article scrapes a floor or a bin all day and never touches food. 410 is the largest single material in our catalog at 57 models, concentrated in the cleaning and utility hardware category. Specifying 304 for a dustpan does not improve the product; it raises the price for a property the application never uses.

Side-by-side comparison

Two things in that table decide most orders. The first is the nickel line: nickel is the dominant cost driver in stainless steel, so the gap between 201 and 304 is a raw-material gap, not a margin trick, and a supplier offering 304 at a 201 price is not offering 304. The second is the magnetic line, which is the basis of the field test described below — with one important exception.

What each grade costs you

The cost difference is real and it moves the retail price. On a graduated five-piece set, the material spread between a 201 body and a 304 body is wide enough to change which retail channel the product can be sold into. That is why the Gold Set in our range — five pieces from 16 cm to 24 cm, model 3201 — is produced in 201: it is built for gift-box and promotional programmes where the landed cost has to hit a supermarket price point, and 201 delivers a non-magnetic, polished, formable body at that cost. Put 304 in the same set and the product becomes a different commercial proposition, aimed at a specialist houseware retailer rather than a grocery chain.

The mistake to avoid is treating the cheaper grade as a hidden downgrade. If the buyer specifies 201 knowingly, prices the retail accordingly, and the retailer's own requirement does not name 304, there is no defect — the product is exactly what was ordered. The defect only appears when a purchase order says 304 and the goods are 201, which is why the verification section below matters more than the price negotiation.

There is also a hidden cost on the other side. Overspecifying 430 hardware as 304, or specifying 304 for a dustpan, raises unit cost without changing the customer experience, and it compresses your own margin for no gain. Grade selection is a matching exercise, not a maximisation exercise.

Corrosion and the shipping container problem

The most expensive grade failure we see is not a specification argument — it is surface staining discovered on arrival. Stainless steel does not rust because it is wet; it rusts when the passive chromium oxide layer is disrupted and cannot rebuild, which happens in three situations: free iron contamination on the surface, chlorides sitting on the surface in a humid environment, and crevices where moisture is trapped and oxygen cannot reach the metal.

Containers on Gulf and Southeast Asian routes combine all three risks. Internal temperatures swing between day and night, so condensation forms on the steel and on the carton; coastal humidity carries chloride; and cartons stacked tight create the crevices. A 430 or 410 article has the narrowest margin here, and a 430 tray that is perfect in a Chaozhou warehouse can show spotting after six weeks in a container. The controls are packing-stage controls: a dry packing environment, no wet or damp cartons loaded, ventilation in the stow, no carbon steel components bundled against stainless, and keeping the factory carton closed until the goods are ready for display rather than opening it in a humid receiving bay. If your own warehouse is not climate controlled, that last point is the one that most often saves a shipment.

How to verify a grade claim in sixty seconds

Bring a magnet. Both 201 and 304 are austenitic and non-magnetic in the annealed state; 430 and 410 are ferritic or martensitic and strongly magnetic. So a magnet reliably separates the austenitic family from the ferritic family, which catches the most common substitution — 430 sold as 304, or 410 sold as 304 in hardware.

The exception matters: after deep drawing, an austenitic 201 or 304 body can become slightly magnetic in the drawn area because the deformation partially transforms the structure. A weak pull at the rim of a drawn saucepan is not proof of 430. Test on a flat, undeformed area such as the base or a handle tang, and treat a strong consistent pull across the whole article as the real signal.

A magnet cannot separate 201 from 304, because both are non-magnetic. For that you need either a mill test certificate naming the heat number and the chemistry, or an X-ray fluorescence reading on the finished article. If a 201-versus-304 distinction matters commercially to you, put it in the purchase order as a document requirement rather than relying on inspection after arrival: specify the grade, require the mill certificate, and where the order value justifies it, commission an independent test on a sample from the production lot.

Which grade for which product

The mapping below follows our own catalog distribution, which has been shaped by what buyers order rather than by what is theoretically optimal.

Cookware bodies and sets

201 for volume retail sets and open stock; 304 where food-contact specification, nickel content or retailer requirement names it. Open stock in individual diameters lets a distributor build a shelf set without paying for a gift box, and the same body can be ordered in either grade, which makes it easy to run a good/better price ladder in one programme.

Trays, buffet and serving ware

430 is the working grade for trays, buffet pans and serving formats, including our rectangular tray range in eight sizes from 18 × 13 cm up to 61 × 41 cm (models 3601–3608). Where the item holds food for long periods, is exposed to acidic sauces, or will be washed in a commercial dish machine with aggressive chemicals, move up to 304 and accept the cost.

Cleaning hardware

410 for dustpans, scoops, shovels and scrapers, including the 66 × 25 cm large dustpan (model 1011), which packs 10 to an inner and 100 to a reference carton. Hardness and abrasion resistance are the performance properties here, and 410 delivers both at the lowest material cost.

Tri-ply: the fourth option

There is a construction that resolves the grade argument instead of picking a side. A three-layer body uses 304 stainless steel on the food-contact interior, an aluminium core for heat distribution, and 430 stainless steel on the exterior. Each layer is chosen for the property it is best at: 304 for the surface the food touches, aluminium because it conducts heat far better than any stainless grade, and 430 because it is ferritic and therefore magnetic, which is what makes the pan work on an induction hob.

We build the wok range this way — 304 interior, aluminium core, 430 exterior, in 22 cm through 30 cm across five variants (models 3241–3245). The commercial argument for tri-ply is that it sells at a materially higher price than a single-layer body while using less 304 than a solid 304 pan, because only the interior layer needs to be 304. The argument against it is that construction quality is invisible: a well-made tri-ply and a poorly bonded one look identical on the shelf but separate, warp or lose their base within a season. Ask for the layer thicknesses in writing, and check that the base is flat after a thermal cycle rather than only on arrival.

What to put in your purchase order

A grade word alone is not a specification. The purchase order should name the grade by standard designation, the construction (single layer or the layer sequence for multi-ply), the thickness or gauge, the surface finish, the edge and handle treatment, and the packing format. Add the document requirement: mill test certificate with heat number, and where applicable the food-contact test report with number, issuing laboratory and date.

Then state the acceptance basis. If the order will be checked on arrival, describe how: magnet test location, thickness measurement points, visual standard for surface defects, and the sample that was approved. An approved sample held by both parties is the single most effective clause in a cookware order, because it converts every later argument about finish and weight into a comparison against a physical reference rather than a description.

Finally, align the grade with the destination. A retailer in a market with a formal food-contact review will want the report to name the material actually used; a mismatch between the certified material and the shipped material is a customs or retail-rejection risk, not merely a quality complaint.

Frequently asked questions

Next step

If you are still choosing between grades for a specific model, send the model number, the intended retail channel and the destination country, and the grade that fits will be confirmed against the specification sheet rather than left to a general recommendation. Requests go to info@dajiangstainless.com or by WhatsApp on +61 415 768 510.

If your range spans cookware, serving ware and hardware, the grade decision will differ by category, and it is easier to settle it once across the whole container plan than per item later. A useful way to frame the request is to send the model list with the retail price band for each product, because the grade that fits is partly a function of where the item has to sit on shelf. Two buyers can order the same saucepan at two different retail prices, and the right grade for each is different. State the price band and the destination, and the recommendation becomes specific instead of general — and the mill certificate requirement can be written into the purchase order before any deposit is paid.
