Re:
Mike,
I'm not that familiar with Deda tubesets but know a little about steels (studied metallurgy). Inox is always a stainless steel. And as you probably know, the main difference between carbon steels and stainless steels is the chromium content - higher, usually 10+%, in stainless or inox steel.
So a comparo' would need to be made with other brand's inox steels.
Hope this helps.
Jon.
