Heat treating information from Mastersmith Bill Burke:

Heat Treatment
Forging: Forge at 1100°C/2012°F. Do not forge below 1000°C/1832°F. You should anneal after forging. SG2 can be forged using good forging practice, however when forging on edge, special care should be taken to advoid delaminating.
Annealing: Anneal at 880°C/1616°F. Cooling speed should not exceed 25°C/hr - 77°F/hr
Quenching: Quench at 1050-1100°C/1922-2012°F. Quench in oil (50°C/122°F) or air (25°C/77°F)
Tempering: Temper at 150-250°C (302-482°F). If you coat such as TiC, temper at 550°C/1022°F

 

Hardness
Annealed: Hrc 30
Hardened: Hrc 62
Sub-Zero: Hrc 62.5

 

After forging/annealing, grind blade to 220 grit (120 grit minimum) finish. Wrap in high temp stainless foil, being sure to seal air tight. Place blade in heat treat oven and ramp oven to 1560 °F and hold 30 minutes. Ramp oven to 2012°F and hold a maximum of 10 minutes. Air, oil or plate quench. Subzero quench at -112°F to -300°F for 60 minutes. Temper two times for two hours each cycle for desired hardness at 300 - 480°F.

 

 

 

Note: results may vary with hardening method and section size. Salt or oil quenching will give maximum results. Vacuum or atmosphere cooling may result in up to 1-2 Hrc lower.
