Hello!

I've been doing some research on CPM 154 and how to heat treat it properly, since I've never done it before. It has led me to ask some potentially silly questions:

What would happen if you didn't wrap the blade in steel foil?

Secondly, would be necessary to clamp the blade between the aluminum plates?

and lastly, would it be so terrible to plate quench the blade between steel plates rather than aluminum ones?

Any help would be greatly appreciated.

Thanks in advance!! :)

You don't have to wrp them in ss foil but you get a lot of scale thats hard to get off, where you can nearly finish one and heat treat it in foil and just lightly clean it up when done treating it. As for the steel blocks you can use them aluminum just pulls the heat out a little faster I dont clamp my plates I just stand on them it only takes a few min then you can hold them

At the temps necessary to austenize many of the stainless steels, the de-carburization that takes place, due to the oven atmosphere, is extraordinary.
This results in excessive post-heat treating labors to end up with a decent blade.

Thank you for the sound advice! Foil it is.
 
we are not talkig about jsut a little decarb witht he proper soak times you will have burned every bit of carbon out (i have had pinholes in foil burn spots)

steel plates will work if thats what you got Al is better but this stil can be air quenched so all is good
