Heat Treatment

Heat Treatment

  1. Annealing
    • Temperature: 840°C – 900°C (1544°F – 1652°F)
    • Process: Heat and slowly cool in the furnace.
  2. Hardening
    • Temperature: 980°C – 1065°C (1796°F – 1949°F)
    • Process: Quench in oil or air.
  3. Tempering
    • Temperature: 150°C – 370°C (302°F – 698°F)
    • Process: Heat after hardening and hold for 2 hours, followed by air cooling.
  4. Stress Relieving
    • Temperature: 200°C – 300°C (392°F – 572°F)
    • Process: Hold at temperature for 1 hour, air cool to remove residual stresses.
  5. Subcritical Annealing
    • Temperature: 650°C – 750°C (1202°F – 1382°F)
    • Process: Heat and slowly cool in the furnace for stress reduction.
  6. Cryogenic Treatment
    • Temperature: Below -80°C (-112°F)
    • Process: Less common, used to improve hardness and stability.
  7. Solution Treatment
    • Temperature: 980°C – 1065°C (1796°F – 1949°F)
    • Process: Quench in oil or air, less common for 420.
  8. Normalizing
    • Temperature: 925°C – 1010°C (1697°F – 1850°F)
    • Process: Air cooling, less common for 420 stainless steel.
