Definition

Iron is a metallic component with the symbol Fe . Iron is a group 8 and period 4 element and is consequently classified as a transition metal. Iron and iron alloys are by far the most common metals and the most common ferromagnetic materials in everyday use. Fresh iron surfaces are shiny and silvery-grey in color, but oxidize in air to form a red or brown coating of ferrous oxide or rust.

Application

1. Pig iron has 3.5–4.5% carbon and contains changeable amounts of contaminants such as sulfur, silicon and phosphorus. Its only significance is that of an intermediate step on the way from iron ore to cast iron and steel.
2. Carbon steel contains 2.0% carbon or less, with little amounts of manganese, sulfur, phosphorus, and silicon.
