Heat Treatments

  • <b>Soft annealing</b>: Slowly heated at 650-700°C, held for several hours, slowly cooled, preferably in the furnace. <br />The soft annealing is most appropriate for machining and cold working and provides the most favorable initial structure for tool hardening.<br /><br /><b>Hardening</b>: Heated at: <br /> 860-900°C, held for 15-30 minutes, air cooled. <br /> 830-870°C, held for 15-30 minutes, oil quenched. <br /><br /><b>Stress relief annealing</b>: Slowly heated 650°C, held for 1-2 hours, slowly cooled in the furnace. <br /><br /> Steel is nitrided in salt baths, gas or powder. The nitriding layer thickness may be 0.01-0.3 mm depending on necessity and method and is usually 0.1 mm.
  • Austenitized at 850 +/- 10°C and oil quenched (usual quenching media for tools are air, gas or salt bath).<br />Tempered at 500 +/- 10°C.
