Answer 2

Answer:

 steel consists of iron plus 17% chromium and 4.5% nickel. This formula has 6.5% manganese to partially substitue for the lower nickel content

Explanation:

Iron fences are only made up of iron, while steel fences contain both iron and carbon. The lack of carbon makes iron softer than steel, which makes iron less durable, requiring more frequent repairs.steel is stronger than iron and it has better tension and compression properties.
