PROPRIETARY ATI 430 Heat Treatments

  • Annealed at 790 - 835°C (1450-1550°F) and furnace cooled at a rate of 28°C (50°F) per hour to 590°C (1100°F) and air cooled. If the annealing temperature does not exceed 790°C (1450°F), an air cool may be substituted for the furnace cool when annealing thin sections.
