Billet


Billet is the product obtained by casting molten steel after it has been refined in a steelmaking furnace. From a manufacturing standpoint, billets are mainly classified into two types: mold‑cast billets and continuous‑casting billets; mold‑casting processes have largely been phased out. Billets are essentially steel products themselves; after further processing, they can be used to manufacture mechanical components, forgings, and various types of steel products, such as Q345B channel steel and wire rod—these are all applications of billets. A billet refers to a semi‑finished product used in steel production and generally cannot be directly supplied for end‑use in society. There are strict criteria for distinguishing between billets and finished steel products; this distinction should not be based on whether a product is an enterprise’s final output, but rather on unified national standards. In most cases, billets and finished steel are relatively easy to differentiate. However, for certain billets that share the same specifications and intended applications as finished steel—for example, rolled pipe billets—their classification may depend on whether they are supplied to other industries, whether they undergo steel‑processing operations, or whether they are further processed on finishing rolling mills.
