Heat Treatments

  • (+QT1) Normalizing or austenitizing from 900 to 980ºC and colling in air; tempering from 580 to 620ºC; (+QT2) Normalizing or austenitizing from 900 to 980ºC and colling in air; tempering from 590 to 630ºC.
  • <b>Quenching and tempering</b>: <br /><br /> Strength level I: Austenitized at 900-980°C, quenched in fluid, tempered at 590-630°C <br /><br /> Strength level II: Austenitized at 900-980°C, quenched in fluid, tempered at 580-620°C <br /><br /> 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
