Can steel be oxidized

Deoxidized steel (Also known as killed steel) is steel that has some or all of the oxygen removed from the melt during the steelmaking process. Liquid steels contain dissolved oxygen after their conversion from molten iron, but the solubility of oxygen in steel decreases with cooling. As steel cools, excess oxygen can cause blowholes or precipitate FeO. Therefore, several strategies have been developed for deoxidation. This may be accomplished by adding metallic deoxidizing agents to … WebGalvanic corrosion means that zinc oxidizes before steel: when it is gone, the steel will rust.
