Steel is the External Physical Pushing metal. An Allomancer burning steel can Push bits of metal away from their center of mass, and can also use steel to sense the presence of metal nearby. Steelpushing is not dependent on magnetic forces or Allomatic power--most metals (with the exception of aluminum and some of its alloys) can be Pushed. Feruchemists can use steel to store physical speed, and when used as a hemalurgic spike, steel steals Physical Allomantic powers.
A steel Misting is known as a Coinshot. Steelpushing is the art of burning steel to push metals away (in a straight line) from the user's center of gravity. There are two general rules for steelpushing, which also apply to ironpulling, its paired opposite. The first rule is that the strength of your push is roughly proportional to your physical weight. This means that larger Allomancers can generally steelpush and ironpull more powerfully than a smaller counterpart. While proportional, the force exerted by an steelpush is much greater than the Allomancer's weight, allowing them to push themselves into the air by pushing on a piece of metal that is on the ground (or is anchored to something that weighs more than they do). The second rule is that metal that is at least partially inside a person's body cannot be affected by steel. Both of these rules can be overcome by a sufficiently strong Allomancer, however.
The steel lines that detect nearby metal manifest themselves on the Spiritual Realm and can be cut or interfered with. It is also possible to use the steel lines to see via the trace metals in everyone's bodies and in the objects around them.
Steelpushing is a fairly flashy ability. It allows the user to fly through the air in quite spectacular ways, using only coins (or other small metal objects) placed on the ground. It can be used offensively, as the name suggests, to shoot metal objects as projectiles. As the coins are much smaller than the Allomancer, they gain quite a bit of speed over time. Steelpushing can also be used defensively, by creating a bubble around the user to deflect incoming metal objects, although in case of very fast objects (such as bullets) it doesn't provide full protection.
When used in conjunction with firearms steel pushing is an incredibly powerful tool. By shooting a regular bullet and then pushing on it as it leaves the barrel the bullet can be given a large amount of force, enough to pierce straight through wood and other cover and kill anyone on the other side unexpectedly.
If someone were able to burn the amount of steel needed to become an Allomantic savant with the metal, they would have better control over their pushes, such as creating a steel bubble that deflects projectiles while not effecting the metal on the user.
A steel Ferring is known as a Steelrunner. Steel is used to store physical speed. Then, by tapping their steelmind, a Feruchemist can move many times faster than a normal human, even one burning pewter with duralumin. While storing speed, a Feruchemist is very sluggish and is described to feel like moving through molasses. Steelrunners can withstand the Gs they are put through, but they can't ignore wind resistance and friction and will burn up if they start running too quickly.
