Heat treat info
(OP)
Short of bringing in all my old books or the ASM heat treat volume, I'm looking for some good online heat treat information for a variety of alloys.
I should mention that while I'm a bioengineer I recently took a job in metallurgy (my undergraduate degree) after about 5 years in a different field altogether. So I'm trying to recall alot of things as I need them for failure analysis and other things I'm doing at work.
Any suggestions?

Ok, now that I am off my soapbox, the following websites are good sources of information on heat treating:
Several references on heat treating, tool steels, etc.

I am actually a member of ASM's local committee still but let my member dues lapse (don't tell anyone!). I will renew my membership.

Hot Working
This steel should be handled like high-speed tool steel. Preheat to 1400/1500ºF (760/816ºC), then heat slowly and uniformly to 1900/2200ºF (1038/1204ºC). Do not forge below 1700ºF (927ºC), and reheat as often as necessary. Cool in a furnace if possible or in warm dry lime or ashes. Anneal after forging; cool to room temperature before annealing.
Allegheny Ludlum is another producer of stainless steel alloy 440A, and their recommendations can be found using the following link:
