AFCEN 20 MN 5 M Heat Treatments
- Normalizing, followed by austenitizing and water quenching.
Tempering 640-670°C / air cooling.
Temperatures shall be measured by means of thermocouples placed on the part. Maximum permissible deviation from specified holding temperatures for the entire part shall be ± 20°C for values above 850°C and ± 15°C for values of 850°C or lower. If, after heat treatment, the channel head does not exhibit the required characteristics, it may be retreated.
