A method for providing a coated strip, which includes the steps of providing a metal or metal alloy strip, applying one or more coating layers on the metal or metal alloy strip and irradiating one or more of the applied coating layers with electromagnetic radiation, wherein one or more of the applied coating layers includes dielectric particles capable of absorbing microwave radiation and wherein microwave radiation is used to selectively heat one or more of the coating layers containing the dielectric particles to dry and/or cure and/or sinter the coating layer.

This relates to a coated substrate for packaging applications including a recrystallisation annealed single reduced steel substrate or a double reduced steel substrate subjected to recrystallisation annealing between the first and second cold rolling treatment, wherein one or both sides of the substrate is coated with an iron-tin alloy layer which contains at least 80 weight percent (wt. %) of FeSn (50 at. % iron and 50 at. % tin) and wherein the iron-tin alloy layer or layers are provided with a chromium metal-chromium oxide coating layer produced by a trivalent chromium electroplating process, and wherein the thickness of the chromium metal-chromium oxide coating layer corresponds to at least 20 mg Cr/m
