As an ingredient

This is used as the main ingredient for almost all of the high-level Blacksmithing epics, as well as some Engineering epics; including the Mechano-hog / [Mekgineer's Chopper].

Aquisition

The main problem facing people who want to make high level or epic items, is the 20 hour cooldown on the smelt.

One solution is to pass the materials on to a friend or alt who can also smelt Titansteel. Although other players may want to use the cooldown for their own materials and items.

A great place to acquire all the materials is in Wintergrasp. Particularly if your faction controls the fortress, the revenants make an ideal source for Crystallized elements. Circling the area with "Find Minerals" on should eventually yield enough titanium ore. The downside being that if your faction is highly outnumbered, it can prove difficult to live long enough to mine these nodes.
