alv.. yea, salt pot is the coolest thing i've had for my basement
workshop.
CPM does make a 52100 steel.. i have no idea if its a true PM steel or
not, i'm not holding my breath for it.. but good 52100 in flat bar
stock is hard to find.
I'll be quenching into the hot salt just above Ms temp. I'm using a
big knife kiln for the high heat. It's not controlled atmosphere so i
must use foil envelopes.. what a paint its going to be tearing those
off before quenching.
Project #1 is an AKM receiver.. shooting for 42Rc after Austenetize at
1550 to 1600F (10min) then austemper at 720F for 30min, no temper
except 350F paint bake later.. its only 1mm 4130 so i just might miss
the 1.2 second pearlite nose if i agitate (think RC boat prop and
motor). since its only 720F i can add water too, just a tiny amount
while its agitating.
I'd like to try some high heat salt later for a 900F temper from the
crazy 2200F aust. temp needed for CPM30V, CPM90V, CPM 3V, etc..
I love those but i'm kind of lost about the optimal hard and tough
matrix of steel around carbides to form thin edge.
