Is steel a rock or mineral?

Answer 1

There's a fundamental problem with the question.

Iron is not a "mineral" in the usual sense of the word. Elemental iron is too reactive to be found in nature as a mineral.

Leaving that aside...

Steel is not "iron". It's mostly iron, with a small admixture of other stuff. So it's not the same as elemental iron, but it's pretty close.

Answer 2

It depends on what you want to do with the metal. Stainless Steel is pretty tough, but it costs a lot, as compared to ordinary steel.

Answer 3

No. It is man-made and a mineral has to be naturally occurring.

Answer 4

Minerals have to go through a lot of processing in order to become steel. You might describe steel as a mineral extract.

Answer 5

Stainless steel(an alloy) is made by combining iron with carbon

Answer 6

No steel is not a mineral.

Answer 7

Iron (Fe).
