Rusting of Iron

Rusting of iron refers to the formation of rust, a mixture of iron oxides, on the surface of iron objects or structures. This rust is formed from a redox reaction between oxygen and iron in an environment containing water (such as air containing high levels of moisture).
To prevent rusting in an electric iron, the plates of the bottom surface and edges are typically made of stainless steel or heavy chromium.
Stainless Steel: It is commonly used because it is resistant to corrosion and rust, providing durability and a smooth, rust-free surface for the bottom of the iron.
Heavy Chromium: Sometimes, the steel is coated with a layer of chromium (chrome plating), which enhances corrosion resistance and gives a shiny, smooth surface that is also rust-resistant. These materials ensure that the electric iron remains rust-free and functions effectively over time.

There is a similar term known as corrosion.

Corrosion

Corrosion is a general term that includes rusting, but not all corrosion is rust.
The process of deterioration of materials due to oxidation caused by chemical or electrochemical reactions is corrosion.
Corrosion can occur on many surfaces, including metals, wood, and skin. Corrosion can be caused by exposure to air or chemicals, and can manifest as discoloration, pitting, or surface deterioration.
