ASTM A 356 Grade CA6NM Heat Treatments
- Heat treatment for mechanical properties:
Normalizing: The castings shall be heated to 1010°C (1850°F) minimum, held sufficiently at that temperature to uniformly heat the castings, and air cooled to below 93°C (200°F).
Tempering: The castings shall be final tempered from 565 to 620°C (1050 and 1150°F).
Stress relieving: The stress relieving operation shall be performed in the same manner as tempering. Temperature shall be between 565 and 620°C (1050 to 1150°F).
Minimum preheat temperature: 10°C (50°F).
