Question

Is steel a pure iron or impure iron?

Answer 1

Answer:

Steel is a Impure iron.

Answer 2

Explanation:

It is therefore ideal for making castings - hence its name. However, it is very impure, containing about 4% of carbon. This carbon makes it very hard, but also very brittle. If you hit it hard, it tends to shatter rather than bend or dent.
