Alright, I'll take care of the Dragon Steel tier, no need to bother yourself with it, but NICE! Here are some ideas if it's not too much trouble.

Elvish Steel [high tier] (also no need to write armor, the matarials are universal for weapons and armor) 

Orc steel (moderately high)

Also note: you can't make Dragon Steel, scientifically it's more like bronze or iron (used to create steel! Wink wink) Dragon Steel is natural.
