Temperature should be equalized at 850oC (1560oF) for 30 minutes to avoid unnecessary temperature variations.
Batch furnace. 30 minutes in furnace.
Quench as rapidly as possible. For optimal results 600°C (1110°F) should be reached within 2 minutes or less.
The material only needs to reach the desired deep freezing temperature, no soaking-time is required.
|60 HRC||175oC (345oF)|
|58 HRC||225oC (435oF)|
|56 HRC||350oC (660oF)|
