Steel arrows are arrows that are stronger than iron arrows.
Steel arrows are not generally used in player killing, but they are common to train with. They are the most used arrow in the class due to their relative cheapness and strength.
Ava's accumulator will pick up your steel arrows if you are not wearing metal armour. It may also generate steel arrows in your inventory or your quiver if it is full.
400 steel arrows is a possible prize from Treasure Hunter[source needed]. They could be converted to 10800 coins, which is 4,000 coins more than selling them on the Grand Exchange.
