Echani Steel was an alloy crafted by the Echani. The alloy was created by combining Durasteel, titanium, and cortosis. The resulting material was light in comparison to its strength and featured cortosis' ability to resist lightsabers. Echani Steel was first forged out of experimentation by the Echani in their attempts to create a material on par with Mandalorian Iron. In this regard the material was a failure as it paled in comparison to the original, it was however much more durable than many other materials. Due to this the Echani kept its existance a secret and used it in the creation of armors such as the Union-type Battle Armor.
