Heat treating it sounds like a good idea.
Here's a thread that summarizes the process. https://www.hobby-machinist.com/threads/heat-treating-annealing-hardening-tempering-metals.26323/

That video link from 2016 is a very good one, the guys presentation is informative & easy to understand, & he explains it well.
These are my homemade 2nd keys.
Chuck on L is a 5”, I turned into a front mount for my SB.
The one on the vise is 2-1/4”.
The 6” lives on the RT, it’s a very old Atlas/Craftsman. Oddly, the chuck key is 7mm allan key.
The one in middle (with the aluminum handle) was probably a project in the high school where this chuck & my SB9 started out. And it still works fine, the key part says W-Germany 7SW
You don’t see 7mm allan keys every day. These 2 were in a box of hundreds of loose keys at a pawn shop.
They were the only two 7mm ones.
Cheers
