MIL 304L Heat Treatments

  • Annealing: Heating 1850 to 2050°F and water quench.
  • Pipe shall be furnished in the heat treated condition. The heat treatment procedure shall consist of annealing the pipe at a minimum temperature of 1900°C (1038°C) and the rapidly cooling the pipe at a sufficient rate so that all the material meets the requirements of the intergranular corrosion test.
