304 stainless steel is ether 304 or not 304 irrespective of where it comes from
304 from china should be just as good as any 304 but its probably just been sold as 304 and in reality is nothing like it, tho in terms of stainless 304 is a pritty sh!tty grade
I export steel from Europe (Bohler/Uddeholm) to China where I get quite a bit of gear made, Asian steel can be very poor in comparison to Swedish or German metals of the same grade. They like to hide my stuff and use it for themselves

Stainless steel which does not oxidise at all is very brittle, which is why 304 is used.
I wont play my 8v exhaust as we all know its a lie
