PROPRIETARY LESCALLOY 6305 VAC-ARC Heat Treatments


  • Anneal: Holding at 774°C (1425°F) for one hour per 25.4 mm of section thickness, furnace cooling to 593°C (1100°F), and air cooling.
    Normalize: Within the temperature range of 927-954°C (1700-1750°F). Material should be held at the normalizing temperature for a minimum of one hour.
    Quenching: Can be air cooled or quenched in oil. Air hardening imparts maximum high-temperature creep and stress rupture properties to the alloy for a prescribed high-strength level. Oil quenching is used to harden large sections or improve impact resistance.
