Abstract

A formed and hardened component made from a metallic material is post-treated by a device for electric resistance heating that has at least one first pair of contact pieces and at least one second pair of contact pieces; contacting a first partial region of the component with the contact pieces of the first pair such that the first partial region is arranged between the contact pieces of the first pair; contacting the second partial region of the component with the contact pieces of the second pair such that the second partial region is arranged between the contact pieces of the second pair; heating of the first partial region of the component to a first temperature by conducting electric current through the component by the first pair of contact pieces; setting the second partial region of the component to a second temperature by the second pair of contact pieces, which is set independently of the first temperature.
