Is spring steel stronger than mild steel?
"Spring steel" is a generic term for steel that has been processed, usually but not always by cold working, to achieve a really high yield strength. Hence it will be able to resist "taking a set" when you load it heavily- or at least more so, by a wide margin, than mild steel.
