Question

The form of iron having the higher carbon content is

Answer 1

Most cast irons have a chemical composition of 2.5–4.0% carbon, 1–3% silicon, and the remainder iron. Grey cast iron has less tensile strength and shock resistance than steel, but its compressive strength is comparable to low- and medium-carbon steel.

Answer 2

Explanation:

Pig iron and cast iron have higher carbon content than wrought iron, but have a lower melting point than iron or steel.
