I would think that stainless pipe would be the best at least you know it wont rust mlid steel pipe will end up rusting

Rust is oxidisation. For oxidisation to occur the metal must be exposed to oxygen (along with other elements). If the cooling system is kept maintained with quality coolant there will be no oxygen and therefore no rust.
Alloy is actually best suited as it disipates heat better.. but very exy!
Mild steel will be ok.
Stainless would be better than mild.
What's your budget??
