Steel rusts because of chemical reactions that occur when it comes into contact with water and oxygen. Iron, one component of steel, combines with water and oxygen to produce hydrated iron (III) oxide, which is the chemi... More »

In conditions where moisture and atmospheric conditions are normal, stainless steel does not rust, but when conditions are more extreme, corrosion may occur. Stainless steel is much more resistant to corrosion than regul... More »

The time it takes for steel to rust is primarily dependent on its exposure to air and water. This exposure can be reduced with the application of protective coatings. Steel rusts more quickly in salt water than in fresh ... More »

Iron rusts when it comes in contact with oxygen and water. It rusts faster in acid rain and salty water. Both oxygen and water are necessary for rusting, which is an oxidation reaction. More »

Zinc does not rust, as rust is caused by a chemical reaction between iron and oxygen. This reaction produces ferric oxide and ferric hydroxide on the surface of the metal. Only iron and its alloys are capable of rusting. More »

Not all metal rusts, but the metals that do rust do so because of an oxidation reaction between the metal and water and oxygen. Oxidation is the process by which a substance incorporates oxygen into its molecular structu... More »

Oxidation is the reaction that occurs by adding oxygen to other materials, often in combination with water. Oxidation is commonly called rust, but this term technically only applies to iron. Oxidation can occur in a vari... More »
