Steel has these properties: it is tough, it can easily be shaped (malleability), cut or made into wire (ductility). Adding certain other elements makes it harder, tougher, and rust-retention capability.

Steel is the backbone of the modern industry. We use a lot of steel objects in daily life. Ships, trains, and most other vehicles, tiny needles and safety pins, machinery and equipment, buildings, etc. utilise steel as a main or sole constituent.
