GB CG6MMnN Heat Treatments

  • Solution heat treated at 1120-1200°C, water cooled.

    The holding time heat treatment is calculated based on the general size of the castings installed in the furnace. When the thickness is less than or equal to 25 mm, the holding time is not less than 1 h, and the holding time is increased by 1 h for every 25 mm of thickness.
