The element used to make steel is iron, which is primarily extracted from iron ore. Steel is an alloy, meaning it is created by combining iron with a small percentage of carbon, typically around 0.2% to 2.1%, enhancing its strength and durability. This process allows steel to achieve a wide range of properties, making it a fundamental material in construction, manufacturing, and various industries. The versatility of steel has made it essential in building infrastructure, vehicles, and countless everyday objects.
