Heat Treating Information:
Preheat: Heat to 1400°-1450° and equalize.

Austenitize: Heat reapidly to 2050°-2150°F. Soak for 30 minutes. Lower austenitizing temperatures maximize impact toughness. Higher austenitizing temperatures maximize edge holding. Quickly plate or air quench to 125°-150°F.

Cryogenic Treating: Cryo is recommended for austenitizing temperatures at or above 2100°F. Cool to -100 °F, removed from cryo and allow blade to warm to room temperature in cool air.

Temper: Temper immediately after cryo or quench if cryo is not performed. Temper for 2 hours. Use the table below to select the rockwell hardness.
