[TheForge] Hardenind H-13

[Peter Fels & Phoebe Palmer]

Dave; It's an air hardening steel and tends to come out 
pretty brittle. It's great for intense hot work cause it 
survives when other tool steels mush out.
EA Chase said " Heat and beat" and grinned. He got away 
with that because he made very beefy tools from it.
I watched him cut slits yellow hot 1" plate under a power 
hammer with a stubby H13 chisel. The chisel turned cherry 
red and continued to cut just fine.
He said, why heat treat when you are going to blow any 
temper the first time you use it?
I draw the temper until i can get a file to grab a little.
The book heat treat is elaborate and requires long 
holding temperature times in a temp controlled furnace.
