Do iPhones with stainless steel (eg iPhone X, iPhone XS, iPhone XS Max) rust when used without a case, especially since I have really sweaty hands? How about aluminum on the iPhone Xʀ? I thought of removing the case as I find naked iPhones really nice!

It’s called ”stainless steel” for a reason. No, the sides of the phone don’t rust. But, because sweat contains salt it can damage other ”non stainless steel” parts instead. For example: The charging port.

You’d have to have a really serious hand sweat problem to do damage to your phones charging port. I think even the charging port is made of non corrosive materials.
 
Stainless steel doesn't contain iron, so no.
Yes, it does.

Generally speaking, Chromium is responsible for its resistance to “the elements.”

There are, however, many different types of SS.

I would imagine the stainless used on the iPhone is 316 which contains a high content of chromium which resists rust. Some low grade stainless will rust with higher contents of nickel etc after extended periods in contact with moisture. You should be absolutely fine with the iPhone. 316 stainless is used in environments like swimming pools and boats as it offers a high resistance.

I’ve known 430 and 304 show signs of rust but it’s highly unlikely this would be used on a mobile phone.
