Sorry if this is the wrong part of the forum, please move if need be!
I am making up some punches for burring over holes, to retain a pin, 4.75mm pin with a simple 3 edge punch. I am waiting on info from the hardeners but have had no joy with a reply so far on hardness.
I have been supplied silver steel to make them from and I will need to harden and temper them, has anyone got knowledge of what hardness and tempering will be best?
