TR steel
From Halopedia, the Halo wiki
TR steel alloy is a type of steel used by the UNSC for large warships.
Background[edit]
TR steel alloy is used to build the superstructure of the ship before it is plated with vanadium steel and, eventually, Titanium-A battleplate.
A curious feature of TR steel alloy is that, as it is exposed to solar radiation over time, it gradually turns from silver to white. It is easy to tell a ship's age by the color of the TR steel in its superstructure.[1]
