Billet is originally steel. After processing, it can be used as mechanical parts, forgings, and various steels, such as Q345B channel steel. Wire rod is the role of billet.
Billets refer to semi-finished products used to produce steel, which cannot be directly used by the society. There is a strict division standard between billet and steel, which cannot be determined by whether it is the final product of the enterprise, but should be implemented according to the unified standard of the whole society. Generally, steel billets and steel are relatively easy to distinguish, but for some steel billets with the same specification and use as steel (such as rolling tube billets), they can be distinguished by whether they are used by other industries, whether they are processed by steel processing process, and whether they are processed by finished mill.
