Abstract
A cooking vessel suitable for being heated by an induction heat source includes a base of austenitic stainless steel. A heat distributing layer is bonded to the exterior of the base, the heat distributing layer being formed of a metal having a high thermal conductivity. A magnetizable layer is connected to the exterior of the heat distributing layer. At least two intermediate layers are provided between and connect the magnetizable layer and the heat distributing layer. Each of the intermediate layers is formed of a material having a coefficient of thermal expansion value between the values of the coefficients of thermal expansion of the materials of the heat distributing layer and the magnetizable layer.
