Temperature should be equalized at 850°C/1560°F for 30 minutes to avoid unnecessary temperature variations.
Austenitizing
Batch furnace. 30 minutes in furnace.
Quenching
Quench as rapidly as possible. For optimal results 600°C (1110°F) should be reached within 2 minutes or less.
Deep freezing
The material only needs to reach the desired deep freezing temperature, no soaking-time is required.
