Steel Pokémon

Steel-type Pokémon are made of, or coated with, steel. 

Steel type pokemon, along with Rock Pokémon  and  Ground Pokémon  are three types that represent earth's minerals (all three are immune to the  Sandstorm  weather condition) with steel representing metal. Steel pokemon are known for their resilance and strength.

Magnemite and  Magneton  were the first pokemon to be reclassified from a single-type ( Electric Pokémon ) to a Steel/Electric dual-type.

To date, there are 5 single-steel-type pokemon.
