PROPRIETARY NiMark Alloy 300 Heat Treatments

Annealing: Annealing and solution treating are performed simultaneously by heating to 816°C ± 10.1°C (1500°F ± 50°F) for a minimum of 30 minutes at temperature, followed by air cooling to room temperature. Age: Usually the alloy is aged at 482°C (900°F) for a minimum of 3 hours followed by air cooling.
