What material used for rail?

Rail is primarily made from steel, specifically carbon steel, due to its high tensile strength and durability, which are essential for supporting heavy loads and resisting wear. In some cases, alloys or stainless steel may be used for specific applications to enhance corrosion resistance or improve performance. The manufacturing process often involves rolling the steel into long, sturdy rail sections, which can then be treated to increase their hardness and longevity.
