Alloy steel

When one or more metals are added to plain carbon steel, the steel acquires certain new characteristics. Depending upon the metals added and the amount of each, the steel becomes stronger, tougher, harder, more heat-resisting, more resistant to corrosion, or acquires some other special properties. Such steels are called alloy steels.

Manganese, nickel and silicon make the steel stronger, tougher or more corrosion-resistant.

Chromium, molibdenum and vanadium in combination with carbon make the steel harder and stronger.

Silicon, manganese, and titanium purify the steel ridding the metal of harmful impurties.

Aluminum and circonium counteract harmful oxides or gases.
