Not to be difficult about it, but a music wire spring has no temper, unless
it's been heat treated. Music wire is not heat treated, and it's not normal
practice to heat treat it.

The steel is 1095, or thereabouts; nothing more eggsotic than that, I'm told.

Your post is helpful, not difficult.
We all need basic references and assumptions checked and re-checked.

Thanks for the post.
