Make the jaws replaceable with w hard set, soft steel and an aluminum set for non maring work.
? ? ? I replaced the hardened, diamond embossed ones on my bench vice with aluminum years ago for a job and never have reinstalled them.

If it's low carbon like 1018ish it won't respond. All that'll happen is it'll get hot until you quench, then it'll be cool.
Only difference will be color.

Bruce, it is a hand vise. Harden it with the torch and oil or water, depending on your steel.
I would harden the whole part, not just the jaw, because it is small enough.

Bruce,
Awesome job on the hand vise!
Where the heck did you find a left hand thread wing nut to pin onto the screw?
Doesn't matter, I like it right down to the handle!
Regarding heat treating: what did you make the jaws out of??
Low carbon? Only option is case hardening.
Anything you might do at home with a torch is likely to give only a very shallow depth. Might call a commercial heat treating place near you to inquire about carburizing.
Explain your situation, they "might" give you a deal.
