A method for selectively forming at least one region of a gasket sheet metal layer made of a spring steel, wherein, for the purposes of facilitating the forming process, the region of the sheet metal layer that is to be formed is heated up inductively for reducing the hardness thereof and the electromagnetic alternating field serving for the inductive heating process is concentrated onto the region that is to be formed, wherein the application time of the electromagnetic alternating field on each part of said region of the sheet metal layer that is to be formed amounts to at most approximately 2 seconds.
