Question

true or false
The presence of carbon in pig iron makes it very soft and malleable.​

Answer 1

ANSWER

The iron obtained from Blast furnace contains about 4% carbon and many impurities in the smaller amount (e.g., S, P, Si, Mn). This is known as pig iron. It can be moulded into variety of shapes.

Cast iron is different from pig iron and is made by melting pig iron with scrap iron and coke using hot air blast. It has slightly lower carbon content (about 3%) and is extremely hard and brittle.
