Notes:
Steels may be quenched in salt, oil, high pressure gas, or forced air. High quench rates will favor toughness and heat check resistance. Holder Block, CSM 2, Kapstar, and CPM Nu-Die EZ are normally supplied already hardened; no further heat treating is required. Holder Block and P20 must be quenched in oil if re-heat treated. |
