    摘要: The invention relates to a method for producing an injection valve for liquids, preferably an injection valve for injecting fuel into a combustion chamber of an internal combustion engine. The injection valve has a valve body, with a valve seat which is formed therein, and a valve needle which interacts with the valve seat in order to open and close at least one injection opening. The injection valve is produced by means of the following method steps: producing the valve body from steel, hardening the valve body, annealing a partial region of the valve body at an annealing temperature. The device for carrying out the method according to the invention has an inductive annealing generator which generates a suitable alternating current for operating a coil, in the magnetic field of which coil the valve body can be heated for annealing.
