Heat Treating Instructions
Hardening
Critical Temperature:
Ac1: 1350°F (732°C) Ac3: 1400°F (760°C)
Ar1: 1295°F (703°C) Ar3: 1240°F (671°C)
Preheating: Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1200-1300°F (649-704°C) and equalize.
Austenitizing (High Heat): Heat slowly from the preheat to 1475-1500°F (802-816C)
Soak for 30 minutes for the first inch (25.4 mm) of thickness, plus 15 minutes for each additional inch (25.4 mm).
Quenching: Oil quench to a temperature no lower than 150-125°F (66-51°C).
