Hi Friends,
I feel quite anxious asking any HT questions, but am compelled to, as I just muffed up a bit.
I am doing my first reasonably controlled HT of a 5160 blade. It was heated to 1525 (the blade was brought up to temp along with the oven), held at1525 for 5 minutes and quenched into Parks 50. It went straight from the quench to another oven preheated to 400. It stayed at 400 for an hour. The next day it was put in the preheated 400 temper oven a second time, but forgotten. It was at 400 for three hours before pulling the plug.
I know I should understand all this stuff, considering all the reading I've done of all you good people's posts, but I'm not sure if the blade is alright or not. My understanding says it is, but my understanding is not as confident as I'd like it to be.
With gratitude and trepidation, Phil
PS - This is my extremely late Christmas exchange blade, so I have to get it right!
