They keep using the words “stainless steel” which is an alloy created to be rustproof by removing the iron out of it. So how exactly is this stainless steel if it rusts?

There are different qualities of stainless steel. Remember kids, it’s stain less not stain never.

I guess there is still iron in it. Looks like they didn’t use an alloy with enough chromium for the application.

Well it has to be workable/formable, weldable and crack resistant under stress. Just welding most stainless mess with its ferrous properties.

Forming it screws it up too. Work hardening after forging can make it magnetic.
