So what would be wrong

OK, so a "friend" of mine got some CPM154, and he decided to forge a blade out of it, then in a forge normalized a couple times lesser temperatures each time then quenched in Park's #50 with the blade at roughly 1550F, what would my "friend" end up with regards to performance of the cpm154? It would of course be below what a proper heat treatment from Paul Bos etc would get performance wise, but what would be wrong with it? What would the simpler (wrong) heat treatment get you as far as structures in the blade?
 
it would simply be too soft, it needs temps up around 1975 to harden properly. What would happen to 1095 if you quenched it 400 degrees below critical?
 
Shame, shame !! At this point I would normalize at least once from proper temperature .This will harden the steel so you have to temper at 1200 F .
Bos or Peter's HT in PA will do the HT properly.

Yup, what Mete said....You may also want to talk to Butch about getting that piece heat treated, he may be able to help you out.

Crucible lists specs for oil-quenching CPM154, although everyone I've asked either air- or plate-quenches it.

I think the issue is getting it to the proper temperature and holding it there long enough. Not to mention the fairly high tempering temps needed. It's an accuracy/consistency thing as far as I know.
