Steel Billet Introduction
Steel billets result from the second stage of the steel production process. They are hot-rolled or forged from an ingot or strand cast. Smaller and longer than a bloom, billets are usually a square cross section less than 36 square inches.
They are used for the manufacture of all 'long' steel products such as bars, rods, pipes, tubes, wire and wire products.
