Neosteel was a very durable and versatile metal alloy. It was mainly composed from vanadium, but there were also a couple of other compounds. It was capable of withstanding various temperatures and very high physical stress. Neosteel was used by Confederacy of Iliard and several other interstellar states for myriad of purposes, the most notable one being the construction of the starships' hulls. However, despite its reliability, it still could oxidize.
