Or is what they are claiming is 304 even 304? There have been chinese chimney products in the past which were misrepresented.'
The Supervent is 304 Stainless Steel and 430 outer. The Shasta is 304 inner and 304 outer. 304 stainless is supposed to be better and more rust proof than 430 from my research. I guess the question is 304 from China worse than 430 from america? I would also be curious if American pipe builders purchase American or China steel? That would be hard to find out.
