Stainless steel iphone X : non magnetic ?

Did anyone else notice that you can't stick a magnet on the supposedly "stainless steel" iphone X ?

According to wikipedia, non magnetic steel exists, but it's more common inside MRI and other medical stuff rather than in consumer devices.

It seems the iphone X's steel is either "ultra quality" or not steel at all. 🙂

It's not really my area of expertise, so, any "material expert" out there care to comment ?
 
Stainless steel isn’t magnetic, perfectly normal. In fact, at my work that’s how we can tell if an enclosure (we build transformers at my place of work) is stainless steel or not....hold a magnet up to it. It’s either cold rolled steel or stainless.

does anyone here have a stainless steel refrigerator?

same deal. can't hang anything on it using magnets (except on the sides, where there's painted regular steel).

Ultra quality? Your URL says “most common”

“However, the most common stainless steels are 'austenitic' - these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it non-magnetic. “

300 series stainless is mostly nickel and non-magnetic
400 series stainless is magnetic and contains more iron and relies on it's chromium level for corrosion protection.

I'm fairly certain Apple chose an alloy such as 316 or 316L for it's products that have exposed metal surfaces.
