Over 80% of the world's ferrochrome, an alloy of iron and chromium, is used in the production of stainless steel. In essence, what does chromium do to iron is fundamentally transform it, providing superior corrosion resistance and enhanced mechanical properties that are essential for countless modern applications.

According to a study published by the National Institutes of Health, citric acid can create a ferrous citrate complex with iron filings, demonstrating its active role in chemical reactions with this metal. This interaction forms the basis for understanding what is the effect of citric acid on iron, which involves chelation, rust removal, and influencing corrosion resistance.
