Steel

materials · engineering · metalworking

Iron plus carbon. Steel is made by mixing iron with a small amount of carbon, which makes it much stronger and harder than pure iron alone. This special combo gives steel its amazing powers.

Built our world. Steel is used everywhere: in skyscrapers, bridges, ships, trains, cars, tools, and even your bicycle. It's one of the most important materials humans have ever invented.

Super strong stuff. Steel can bend a little without breaking, holds its shape under pressure, and doesn't snap easily like pure iron would. This mix of strength and flexibility makes it perfect for building big things.

Cheap and common. Unlike rare metals, iron and carbon are found all over Earth and don't cost much to mine and process, so steel is affordable enough to use for almost anything.
