Temperature should be equalized at 850oC (1560oF) 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.
