I heat treated and plate quench my first blade of Elmax
I used this:
in the cold oven,
fast ramp up to 1560F, hold 20 minutes
fast ramp up to 1980F, hold 30 minutes
plate quench
RC tests were: 63.5, 64.5, 63.5
Cyro 8 hours, RC tests were: 64.5, 63.5, 64.5
temper 2 hours each at 390F, RC tests were: 61.5, 62.5, 61.5
I didn't get any pics of the grind or heat treat. (I did shoot video of it though. Later for that however.)
I was going to draw it back to 59/60 but I think I'll give this a go. I hope to get to finishing it up this weekend and then I'll post a few pictures.
