Lightning Steel Ingot are made by a cooldown also named Lightning Steel Ingot, which requires 10x Ghost Iron Bar, and has a research aspect. With the research you can learn a plethora of new patterns, such as the Crafted Dreadful sets and the 522 patterns that require Haunting Spirit from Throne of Thunder.
Crafting with Lightning Steel
Lightning Steel is actually only used in a grand total of 18 patterns. The first 6 you get when first completing the chain from killing Itoka. Each of these "Phase 1", ilvl 463 weapons are then used as a reagent in crafting "Phase 2" weapons, epics of ilvl 476. From there, those Phase 2 items are used as reagents in crafting ilvl 502 (raid finder) weapons, that have item models of old no longer obtainable weapons for potential transmogging.
Phase 1 requires 5 Lightning Steel Ingot, 3 Spirit of Harmony, and 2-3 Living Steel. All these patterns are learned initially when doing the quest from Itoka. All phase weapons are BoE (see chart below for links), and are required as a reagent, and also unlock the patterns for the Phase 2 weapons.
You learn the recipe for all Phase 2 weapons by crafting their Phase 1 counterparts. Mats are 10 Lightning Steel Ingot, 6 Spirit of Harmony, and 4 or 6 Living Steel.
You learn the recipe for all Phase 3 weapons by crafting their Phase 2 counterparts. Mats are 15 Lightning Steel Ingot, 9 Spirit of Harmony, and 6 or 9 Living Steel.
As you can see the mats to craft an ilvl 502 weapon are astronomical, so there will probably be a limited market for these, at the price they'd go for. The chart below summarizes the evolution models with Wowhead links. Phase 3 is not on Wowhead yet, so they are battle.net links.
