[TheForge] Suggestions needed for scroungeable steel

Wed Nov 19 16:58:01 2003

Well, actually Chuck knows what he's talking about here.  I'm sure he
doesn't mean "mild steel" in the sense of NO carbon content.

Chuck - what is the carbon content of the steel you use in your
knifemakers' anvils?

No Chuck it would not! Super Quench is not magic just a fast quench. 
To do
the job the steel has to have the carbon content.  Hey you know that. 
Might
work with 1045, but 1060 would be better.  1080 would be great.  4140
or
other alloy steels could also do the job, but not mild steel, even the
evil
A 36.
