John,

I know I'm not Grant and your question was directed to him.  But ... you 
can get the basic heat treating information from the Principal Metals site:

http://www.principalmetals.com/properties/result.asp?Family=Alloy+Steels&MetalName=4340

The Principal Metals site (http://www.principalmetals.com/) has a lot of 
good basic information about various alloys of steel and other metals.

It's worth bookmarking in your browser.
