Stainless has chromium added. Iron is still the main element. Different stainless steels have various other elements added, like molybdenum. There’s a wide range of SS for various purposes. Not sure which one they used. There’s also a finishing process called passivation that should be used to reduce the likelihood of corrosion
You are absolutely right, just for clarity:
Chromium needs to be > 12 weight-%. If you take 18 w-% Cr and 8 w-% Ni you get an austenitic steel which is (normally) neither magnetic nor able to be hardened.
And if you add 12 w-% Cr, you remove 12 w-% Fe. So formally this is right-ish too…
