If for some reason you have to drill, cut, whatever to remove it, softer is better.
Copper or brass nuts will not freeze on rusted steel. No galvanic corrosion with the brass or copper.
A clamp or band or pipe that is stainless is great just not the fasteners.

There are several different grades of Stainless steel.
