Preheat: Heat to 1,550-1,600°F. Equalize temperature.
Austenitize: Heat to 1,950-2,050°F, soak times for the different austenitizing temperatures are listed below: 1,950°F = 30 Minutes 2,050°F = 20 Minutes The recommended heat treatment is to austenitize at 2,050°F then quench to below 125°F. Cryo if desired. Temper twice at 500°F for 2 hours minimum each temper. Cool to hand warm between tempers.
Quench: Plate, air or positive pressure quench (2 bar minimum) to below 125°F, or interrupted oil quench to about 1,000°F, then air cool to below 125°F.
Temper: Double temper at 400-700°F. Hold for 2 hours minimum each time. Additional Information: Referring back to Larrin's previously mentioned S60V article, the following is a quote where Larrin discusses testing higher austenitizing temperatures: To see the steel’s potential for high hardness I also tried heat treatments with 2100°F for 15 minutes and 2,150°F for 10 minutes, each followed by a plate quench, cryo, and temper at 300°F. The 2,100°F heat treatment led to 64.3 Rc and 2,150°F resulted in 65.0 Rc. Therefore very high hardness levels are possible for those knifemakers that are interested. Based on the results of Larrin's testing, more testing should be done.
