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 780-810°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 800-830°C, oil quenched. <br /><br /> <b>Stress relief annealing</b>: Slowly heated at 600-650°C for 1-2 hours, slowly cooled in furnace.
  • Austenitized at 790 +/- 10°C and water quenched.<br />Tempered at 180 +/- 10°C
