Is steel made of living things?

Answer 1

No, nor is it made of things that used to be living. Iron is created in stars like our Sun, and millions or billions of years later makes up a good part of planets, other stars, and so forth. Then people smelt the iron and in the process, make steel from it.

Answer 2

No, steel is not made of living things. It is a man-made alloy consisting primarily of iron and carbon, often with other elements added to enhance its properties. The production of steel involves heating and melting raw materials like iron ore and coal in a blast furnace to remove impurities and create the final product.
