Mild steel is the best choice, it will be alot stronger than stainless.
Stainless will corrode less because its less reactive, but also its equipotential is closer to Aluminium. However corrosion is slow on these. I've never changed or snapped any on a red block. I have tried stainless metal locking (aviation) nuts, they seem ok.

I'm dumb. I thought alloy was different from aluminium. So the 16v head is the exact same material? Before I bought my car someone on us Volvo forums told me I should stay away from the GLE 16v because of the aluminium head.
So, it's not absolutely necessary to change them everytime you mess with them? But i guess you should at least have spares just in case. I thought i read it was advisable to change them because they are probe to snapping.
