Just Google "Live Steam Boilers Duplex Stainless Steel" or just "Duplex Stainless Steel" and you can read the numerous articles written about this material and what has been done with it.
I am not trying to influence anyone one way or the other.
But note the specific "Duplex SS." This is a unique alloy with stainless properties, and not your "undefined" stainless alloy.
And research and testing backs up the usage in boilers, as a superior material.
Probable expensive, too.
