WebAs the chromium corrodes, it forms a protective chromium oxide layer on the outside of the steel that greatly slows the corrosion of the iron in the steel. It keeps your stainless steel pots and pans looking shiny, not rusty, even when they're exposed to water every day when you cook with them or wash them. 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.
