Fuck, the fat faggot with bitch tits really is RETARDED.
Fatrick's fridge is made of
austenitic stainless steel, probably standard kitchen-appliance-grade 304, which contains 18% Chromium and 8% Nickel. It's not non-magnetic because of the nickel; it's non-magnetic because the crystal structure (austenite) is non-magnetic. (For complex reasons that have to do with how iron atoms are aligned in an irregular way in austenite.)
You can make non-ferromagnetic austenitic stainless steels with very low or even zero nickel, e.g.:

And lol at "ferritic crystal structures." Ferrite is something very specific: It's a type of steel microstructure, like austenite, martensite, pearlite, and others.
Ferrite is magnetic, so Fatrick's fridge is almost certainly not made of a ferritic steel.
I like the punchline "it's all nickel's fault," when nickel has literally nothing to do with anything.
What a buffoon.
