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 ...

Varying amounts of other alloying elements like Ni, Mo, V, Ti, Ni, etc. may be added to obtain certain specific properties. It exhibits extraordinary corrosion resistance due to the formation of a very thin layer of Cr2O3 on the surface. WebChromium metal (Cr) is a bluish to steel-gray brittle solid, often seen in gray powder form that burns if flame heated.
