What’s better steel or iron?

Steel is stronger than iron (yield and ultimate tensile strength) and tougher than many types of iron as well (often measured as fracture toughness). The most common types of steel have additions of less than . 5% carbon by weight. Other elements commonly found in steel are manganese, silicon, phosphorus, and sulfur.

What is raw iron called?

Wrought iron, one of the two forms in which iron is obtained by smelting; the other is cast iron (q.v.). Wrought iron is a soft, ductile, fibrous variety that is produced from a semifused mass of relatively pure iron globules partially surrounded by slag.
