Yes, but not all stainless steel uses nickel. Chrome and molybdenum, and any other number of metals can be used as well.
The highest quality warships will use 2% to 5% nickel because of its extra hardness, but any ship made nowadays will be made of straight iron, with a 300 pound zinc anchor weight that reduces rust (its just way cheaper and works)

Most stainless relies on nickel. The 4xx ferritic series does not, but the austenitic 2xx and 3xx series require it to retain the microstructure over the entire temperature range, and the while the martensitic series uses less nickel, the better precipitation hardening PH alloys of the martensitic series like 17-4PH and 15-5PH rely on nickel. Bottom line is that most of the best stainless alloys require, and use, nickel - in amounts from 4% to 10%. By volume >85% of stainless requires nickel.
Ships use high strength low alloy HSLA steel, not iron.

I just think your message would be be more portable if you were more precise about some of your language.

Better places still electroplate tin over iron. Food grade tin in ingots is regularily sold.

i'm missing something here. US dimes and quarters haven't changed composition, right? Even a dime has much more nickel than 1 mg...it's more like 188mg.

It's been a while since I've sorted any, so I figured what the hell.
