Hi Guys,
I am a newbie and got my first chunk of h13 hardened and triple temper professionally.
The color changed from silver to almost black with a small patch that had been sanded back to the bare metal.
Tested and is average 54.1 RC.
My question is :
what is the black color ?
do I need to sand it off, and how?
Do I radius the corners before or after hardening?
Thanks,
Jon
