DIN 1.1118 Heat Treatments

  • (+QT1) Normalizing or austenitizing from 880 to 950ºC and colling in liquid; tempering from 520 to 570ºC; (+QT2) Normalizing or austenitizing from 880 to 950ºC and colling in liquid; tempering from 600 to 650ºC; (+QT3) Normalizing or austenitizing from 880 to 950ºC and colling in liquid; tempering from 650 to 680ºC.
  • Quenching and tempering:

    Strength level I: Austenitized at 880-950°C, quenched in fluid, tempered at 650-680°C

    Strength level II: Austenitized at 880-950°C, quenched in fluid, tempered at 600-650°C

    Strength level III: Austenitized at 880-950°C, quenched in fluid, tempered at 520-570°C

    The temperature for the stress relief heat treatment should be at least 20°C, but at most 50°C below the applied tempering temperature of the casting
