Question

Which is the fastest Steel-type Pokemon?

Answer 1

If you count legendaries/sub-legendaries and forms or regional forms, then Zacian-Crowned is the fastest Steel, at 148 Spe.

If you count legendaries/sub-legendaries but not forms, then Kartana/Durant at 109 Spe. If regional forms count, Alolan Dugtrio at 110 Spe.

If you don't count legendaries/sub-legendaries nor forms or regional forms, then Durant at 109 Spe.

Hope I helped!

Answer 2

As of Gen 7, Alolan Dugtrio is the fastest steel type Pokemon, with 110 speed.
If you count forms, Arceus-Steel is the fastest steel type with 120 speed.
If you count alolan forms as form, then Durant and Kartana is the fastest steel type Pokemon with 109 speed.

Comments

Alolan Dugtrio is also an alternate form, though. The fastest steel Pokemon without forms are Durant and Kartana.

If Megas counted, then it'd be Mega Lucario.

If legendaries count, probably Zacian.

Answer 3

Steel types as a general rule are not very fast
The fastest is Durant at base 109, followed closely by Cobalion at base 108
