Abstract

A method for producing a rigid magnetic circuit component for an electromagnetically operable valve includes: a) providing a base element made of a magnetic or a magnetizable material, b) complete first heat treatment of the base element, c) a local second heat treatment of the base element so as to form a subregion having a microstructure of martensite and residual austenite in the otherwise martensitic base element, and d) installing the finished processed base element as the magnetic circuit component in a magnetic circuit.
