Chromium imparts resistant to corrosion
WebSep 19, 2024 · Stainless steels are remarkably resistant to corrosion because they usually contain a significant proportion of chromium, nickel, or both. In contrast to these metals, when iron corrodes, it forms a red-brown hydrated metal oxide (\(\ce{Fe2O3 \cdot xH2O}\)), commonly known as rust, that does not provide a tight protective film (Figure ... WebIt comprises a wide range of iron-based alloys, but unlike conventional steel they are resistant to corrosion and do not rust when exposed to water alone. The alloying element that makes steel ‘stainless’ is chromium; however it is the addition of nickel that enables stainless steel to become such a versatile alloy.
