Beschreibung
Zusammenfassung:	A compound body comprises a steel base element on which is deposited a heater layer. The base element is made of a precipitation hardening steel. In the form of a manifold or material feed tube in a hot duct system, said base element comprises a round or convex surface receiving the heater layer. This heater layer is a compound layer having several strata and/or strata elements which are thick film pastes or sheets and in such form are consecutively deposited, dried and baked-on. The pre-compression generated in this process in the heater layer is increased in controlled manner by precipitation hardening the base element.
