That will do it... Do you buy it in T state and machine it carefully with lots of coolant or do you heat treat it yourself?
If you want to over-do it then something like D2 will work I would have thought. EN24 is much nicer to machine though!
P.S as a MechE I am very much liking this new forum section.

Both, I have a little PID electric HT oven I built a while ago.
I have a lump of 50mm dia D2 on the rack next to me for a project, it is always fun to machine and gives a nice finish as well. Probably an overkill for firing pins and strikers :)

Like I said... if you wanted to over do it....
Electric HT oven is something I want to do at some point. I make knives as a sideline hobby. But I use a propane forge at the moment for heat treatment. Having an electric one would be so much easier.

This is/was the start of mine, I need to update the Journal to show where it is now.
Very nice! Good temperatures too! Couldn't quite forge weld but for anything else its bang on.

Yes, in the real world 1000C ish is ample for most things and I have no plans to become a blacksmith.e specially as there is a forge being built maybe 100 yards away or less.

Demo, for those whove never seen it burn:

Note that titanium is not alone in geing a flammable metal.
Set fire to a clump of steel wool and see if you can put it out! Better still, if you have access to a really hot flame, try it with aluminium---and you definitely will not be able to put this out.
A powdered mixture of iron and aluminium swarf was used to surround the ends of railway lines and, when ignited, would weld them together.
