Froststeel is term which was introduced with the release of Wrath of the Lich King 
. Despite what one might assume based on the name, there are no Froststeel ore or bars currently in-game for players to mine or craft with. The only reference to this mysterious type of metal is that the name is applied to two in-game items:
- [Froststeel Lockbox] - A world drop which can be dropped anywhere in Northrend.
- [Froststeel Tube] - A crafting material created by engineers by combining Cobalt Bars and Crystallized Water. It is used in a handful of Wrath of the Lich King engineering recipes. This item also has a chance to be dropped by
Flame Leviathan in Ulduar.
