“Stone and bone are strong. The ore we find is strong, but it can be made stronger. Steel is the strongest, just like us. We are the strongest, and we use the strongest steel in the universe!”
- Horde worker

Steel is a metal alloy that is made by combining the iron from processed ore with other elements. The most common element used in this process is carbon. Other elements used can include manganese, chromium, vanadium, and tungsten.

Steel is the most common commodity in the universe. It is used by all races and factions. The average production of steel over the course of an average planetary year is between one and two trillion tons. The reason for this is that steel is used in many different structures and components. It can be used in planetary structures and weapons.
