Pak China Steel

Pig iron is a metal material that results when iron ore, low ash coke, and limestone are melted together under intense air pressure. When the combined material cools, it forms a high-carbon product known as pig iron. The cooled material is rarely used by itself, as the large amount of carbon makes the material brittle and unstable.
