Current Topic:
Selection Criterias for Hardened and Pre-hardened Tool steel for Injection mold

Gs, it depends on whether you want to do the heat treat hardening before or after you machine the die.  If you can use a die that is only about mid Rockwell C 40's, then use the pre-hardened material.  If you need higher hardness in your die, then you will need to heat treat it after machining, and you should start with the annealed material: then you harden it to greater than HRC mid 40's.
