    Heat Treating of HighAlloy White Irons :: Total Materia

    An austenitizing heat treatment usually comprised heating at temperatures between 750 and 790°C (1380 and 1450°F) with a soak time of 8 h. Air or furnace cooling, not over 30°C/h, was conducted followed by a tempering/stressrelief heat treatment. Refrigeration heat treatment is the more commonly practiced remedy for low hardness today.

    Induction hardening Wikipedia

    Induction hardening is a type of surface hardening in which a metal part is inductionheated and then quenched.The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole.
