Steel is a strong and durable metal made primarily from iron and carbon. It is widely used in construction, manufacturing, and various industries due to its high tensile strength and resistance to corrosion. Steel can be found in structures like bridges and buildings, as well as in everyday items such as cutlery and tools. The production of steel involves processes like smelting and alloying, which enhance its properties. Different types of steel, such as stainless steel and carbon steel, are tailored for specific applications. This versatility makes steel a fundamental material in modern engineering and architecture.
