HT cpm154

[Traok]

Hey guys quick question I hope....

I just recievd my first bar of cpm 154 1/8" , have my blade ground out and ready for HT..

I checked the net for some info and was hoping I could run it by you to verify before I did it.

a) Heat to 1900 for 30 to 60 minutes ( I cant hold temps so I figured Id start the stop watch at 1900 for 30 mins)

b) Oil Quench ( Just dunk it like anything else in tranny fluid)

c) Oven heat 400 degrees for 2 hours

D) Oven heat 400 degrees for 2 hours

That should be it ?

Thanks

I know a bad ht = knife melt down thats why Im asking, and unfortunatly sending em out aint an option at this point

Are you using a H/T kiln or somethin else.Here is how I do my cpm154.
Clean thoughly
Wrap in foil
1200 deg for 20 min.
1600 deg for 20 min
1950 deg for 40 min.
Platte quench
Temper at 420 deg 2 X 2hrs
Consistantly get 59-60 Rc

Yes using a kiln but it has no temperature controll. Plug it in and temp ramps up. It tops out at 2000 degrees.

I should do more research in plate quenching seems like thats the way to go.

Now would it still be the same to time the 40 mins at 1950 even if the temp is ramping towards 2000. As at that stage the temperature is just creeping. So I think it would take 30 mins to 40 mins to go the extra 50 degrees.

Yea my normal ht goes..

Clean with alchol
Place 4 small peices of paper in packet
Wrap in foil
Double seal all edges
Rubber mallet edges
Place in oven
when temp is hit pull it out and quench appropriatly
then oven temper

But I have never done CPM154 so I was not familiar with a proper ht for it. ( I know zero quench etc.. but I dont have that setup )

Your process is good, the thing I've found is CPM154 need atleast 40 min of soak time to get the most out of it.After the longer soak it finishes better so I guess it get better into solution with the longer soak.
