Heat Treating Question

[GLDOYLE]

ALTHOUGH THIS IS NOT ABOUT KNIFE BLADES I
HOPE SOMEONE CAN HELP ME . A FRIEND IS
MAKING A SET OF DIES TO USE IN A PRESS BRAKE
TO STAMP LOUVERS IN SHEETMETAL AND HE WANTS
ME TO HEAT TREAT THEM . WHAT WE DON`T KNOW IS
HOW HARD THEY SHOULD BE . WE WANT THEM TO BE
HARD ENOUGH TO LAST BUT NOT BE BRITTLE . THE
STEEL IS O-1 AND THE SIZE 1/4 X 5/8 X 6" AND
1/4 X 3/4 X 6" . ANY IDEAS OR SUGGESTIONS ARE
APPRECIATED.
THANKS ,
LARRY

Well its not as high tech as knives, If your starting with annealed o1 heat to non Magnetic quench in oil and temper to approximately 600 degrees or till the piece starts turning blue.hope this helps.
