A billet is a piece of semi-finished solid metal form, generally having a cross-section of 105 to 230 square centimeters, and rolled into finished ‘long products’ such as bars, rods and, channels. Billets are created directly by intermediate castings or extrusion or indirectly via hot rolling an ingot or bloom produced in a steel mill that needs further processing before being a finished good. Rolling and drawing are two other processes through which billets can be processed. In simple words, a billet is an unfinished metal that needs to be processed further before becoming finished goods. It can be rectangular, circular, or square in shape. They are used to manufacture steel bars. Final products include bar stock and wire. Billets are sold as cut lengths or coil, and usually, have an area less than 36 square inches. Billets are also known as bar stock. The other types of semi-furnished casting products are ingots, blooms, and slabs.
