Ferrous Metals

A ferrous material is the one in which iron is a main constituent. Iron ore is first converted into pig iron and then pig iron is subjected to various metallurgical processes to mix different percentage of carbon and to get the following three useful ferrous materials: 1. Cast iron—carbon content 1.7% to 4.5% 2. Wrought iron—carbon content 0.05% to 0.15% 3. Steel—carbon content 0.25% to 0.25%. All ferrous materials contain about 0.5 [&hellip
