The Steel type is one of the eighteen types. Prior to changes in Generation IV, all damaging Steel-type moves were physical, but they may now also be special depending on the attack.
The Steel type was introduced in Generation II, along with the Dark type.
In Generation II, the Steel type was created to balance out the previously overpowered Normal and Psychic types, as both types are resisted by Steel. Although the number of Steel's resistances decreased from 11 to 10 in Generation VI (including the added resistance of the newly-created Fairy-type), Steel remains the most resistant type. Steel types also cannot be poisoned (except by Twineedle in Generation II or if poisoned by a Pokémon with Corrosion) or damaged by a sandstorm.
Normal/Steel, Electric/Steel, and Ghost/Steel are tied for the most resistances, having 12 resistances each, although there are currently no Pokémon with the combination of Normal/Steel.
Steel-type Pokémon, on average, have the highest physical Defense among all Pokémon and among fully evolved Pokémon.
While some Pokémon resist Steel-type attacks, many of these Pokémon are weak to Ground, so combinations of Steel and Ground attacks tend to work well.
