18/10 vs 18/0 Flatware

18/10 means 18 percent chromium and 10 percent nickel; 18/0 means 18 percent chromium and no nickel. The nickel is why 18/10 resists rust better and has a warmer shine, and it is the reason 18/10 costs more. Buy 18/10 for the set you expect to keep, and 18/0 without guilt for an outdoor set, a party set or a first apartment.

The two grades, side by side

What the numbers actually describe

Both numbers describe the alloy, not the quality of manufacture. The first is chromium, which reacts with oxygen to form the thin passive layer that makes steel “stainless” in the first place. At 18 percent, both grades have plenty.

The second is nickel, and nickel does two things: it stabilizes the steel in a structure that resists pitting better, and it gives the surface a warmer, less clinical shine. Take the nickel out and you get a cheaper, slightly harder, slightly more magnetic steel that is more likely to spot if it is treated badly.

The magnet test

Nickel-bearing 18/10 is austenitic, which in practice means a fridge magnet will not stick to a fork. 18/0 is ferritic and the magnet holds. It takes two seconds and it is the only way to check a set whose listing is vague.

One caveat worth knowing before you distrust a good set: knife blades are usually a different alloy from the handles, chosen because it hardens and holds an edge. A magnet sticking to a knife blade on an otherwise non-magnetic set is normal and is not a sign you were sold 18/0.

Where our picks sit

Of the four sets here, the KINGSTONE listing is the one that states 18/10 explicitly — 40 pieces, service for eight, hammered handles, dishwasher safe. The other three list “stainless steel” without naming a grade, which is extremely common and is exactly the situation the magnet test exists for. We do not assign a grade a listing does not claim.

• KINGSTONE: stated 18/10, service for eight. The set to buy if you want this settled.
• DEHOV: stainless, mirror finish, service-for-eight options. Everyday value.
• KIKCOIN: stainless, large piece counts, service for eight and twelve. For big households.
• BEWOS: stainless, colored and matte finishes, service for four and eight. For when the finish is the point.

How to make either grade last

• Do not leave it wet in the basket. This causes more spotting than grade ever does.
• Keep it away from other metals in the dishwasher. Steel touching aluminum in a wet basket pits both.
• Rinse off salt and acid before they sit. Vinaigrette and lemon left overnight will mark 18/0 and can mark 18/10.
• Load handles down for forks and spoons, up for knives. Cleaner on the business end, safer on unloading.

For the sets compared on their own merits rather than on alloy, the flatware roundup goes through all four in full.

Grade is the first of five decisions. How to choose flatware covers the other four — weight, finish, piece count and handle shape — in the order they matter.
