WebAug 25, 2024 · How does chromium prevent corrosion in steel? When oxygen reacts with iron, a red oxide is formed. Chrome undergoes the same corrosion process as iron, but the oxide it produces, Cr2O3, creates a protective coating on its surface that keeps oxygen from destroying the metal. Chromium’s negative electric potential (-) makes it a passive layer.
