Only iron and metals that contain iron, such as steel, get rusty. Iron rusts when it comes into contact with water and air. This is because the water and oxygen in the air react with the iron. This reaction creates a new substance—the reddish- brown flakes of rust. Painting iron can keep it from rusting because paint helps to keep out air and water.
