I realize this stuff has been gone over ad nauseum My simple question is what it actually means.
Normalize at 1550-1650°F for 10-15 minutes and air cool.
Anneal at 1400°F for 30 minutes, cool at 600°F/hr to 1200°F, air cool.
Austenitize at 1525°F for 10-20 minutes depending on stock thickness, quench in oil.
Temper at 300-450°F to desired hardness.
So, Ok my blade is cut out, primary grind done, file work done, Gimping done, holes drilled. ready to heat treat.
I have a brand new never used Even heat Lb 27 this will be the inaugural run.
what do they mean by Anneal is the knife blank already annealed? And where it says Austenitize That is simply running it up to Crit temp soak for 10 to 20 min then pull out and dunk in my parks 50 .Then Do I but it right back in the oven at 400 to 450 for an hour ( some folks say do that twice) or do I air cool it first then put it in the oven at 400 to 450??? the reason I ask that is if my Kiln is at say 1525 it will take a bit to drop ( I am assuming) to 450. Or am I dunking in parks 50 and slamming it in the wife's oven while still hot (she loves that wonder why her cakes taste like oil LOL) or do I have time to cool the kiln?? any clarification or tips would be appreciated.
Thanks Jerry
