Iron and steel differ in their composition and properties. Iron (Fe) is a chemical element and the most abundant element in Earth’s core. It is found in various minerals and is extracted through smelting. Steel is an alloy primarily composed of iron and carbon, with the carbon content typically ranging up to 2 percent. This addition of carbon significantly alters the properties of iron, making steel a more versatile and widely used material.

Iron and steel have distinct applications based on their properties. Iron, in its pure form, is not commonly used in engineering because of its softness. The presence of carbon in steel enhances its hardness and strength, making it suitable for a wide variety of applications, including construction and manufacturing tools.
