鋼 (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. Different types of鋼 can be produced by altering the carbon content and adding other elements, which gives it various properties suitable for specific applications. 鋼 is essential in creating structures like buildings, bridges, and vehicles. Its versatility allows it to be shaped into different forms, such as sheets, beams, and rods. The production of鋼 involves processes like smelting and alloying, which are crucial for ensuring its quality and performance in various uses.
