Billets, or ingots (as they sometimes referred to), are not of practical use until they have been formed
into more functional shapes and sizes. While they have already been put in the furnace, they still require
a series of shaping and molding procedures such as hot and cold working, milling and cutting before they
are sold in hardware stores, or used for different applications. The unformed billets, however, can be used
in striking currency such as coins and as reserves, similar to gold bars.
Steel billets have distinct characteristics as compared with already furnished steel bars and products. Billets
have a specific grain structure, which enables the metal to be processed more intricately. Steel billets are also
known for their malleability and ductility, especially when exposed to varying temperatures during shaping and molding.
