What are torsion bars typically made of? I was going to guess 5160 or 8136 (or whatever that 8100 number is) but a quick Google shows more hits for
4340 than either..?
I suppose that makes more sense than 5160 since that's a water-hardening alloy, no? Could be hard to evenly harden a 1"+ dia. bar...
In case you're wondering, I want to anneal some of a scrap bar I have, chop off sections and forge it into stuff.
