Heat Treatments

  • <b>Normalizing</b>: Heated at 800°C. <br /> <br /> <b>Soft annealing</b>: Slowly heated at 680-710°C for 4 hours, slowly cooled, if possible in the furnace (to at least 500°C). <br /> <br /> <b>Hardening in water</b>: Slowly heated at 770-800°C, quenched in water. The quenching water should be 20-30°C and not colder than 20°C. <br /> <br /> <b>Hardening in oil</b>: Slowly heated at 790-820°C, oil quenched. <br /><br /> <b>Stress relief annealing</b>: Slowly heated at 600-650°C for 1-2 hours, slowly cooled in furnace.
  • Hardening: 780+/-10°C (25 +/-1 minutes), water quench;<br />Tempering: 180+/-10°C (60 minutes).
