Hi guys,
Well i just got in some 3/16" 52100 bar stock from Aldo and my plan is to start some large pig stabbing knives this weekend with it. I am planning on doing a WIP for anyone interested in here who might wanna see it
My question is about the heat treatment process of 52100, after doing multiple searches on the forum here this is what i have come up with
I am planning on cutting the steel and drilling and doing primary grinds until im about .060" thick on the cutting edge. Then i was going to normalize 3 times at 1200deg letting it cool to room temp in between each cycle. Then i was going to anneal by heating it to 1450deg and immediatly turning my Evenheat oven off and allowing it to cool slowly over night. Then i would heat treat at 1520deg for 8 minutes and quench in Parks 50 oil. The blades would satanite coated for differential hardening. I was going to temper first at 420deg for 2 hrs and then LN cryo treat over night, then double temper at whatever temp you all recommend.
can anyone recommend anything better to do or if i am way off base on any step
here???
thanks
steve
