Ive been researching cmp 3v a lot lately and have come up with several heat treat reipes..Mainly two..Seems that some like the high aust. temp and high temper of *roughly 975*-1000* and some like a lower aust. temp with cryo and lower tempering of about *400..Id like to hear your thoughts on this. Also is a full Ln cryo needed to reduce RA in the second recipe I mentioned or would a sub zero quench work?
