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.

In the manufacturing of tooling, steel billets serve as the raw material from which the tool is formed. These billets are usually made from high-quality steel alloys that exhibit excellent strength, durability, and wear resistance properties. These characteristics are crucial for tooling applications as they ensure the longevity and performance of the tools. Once the steel billets are obtained, they undergo a series of processes to transform them into tooling components. The first step is to heat the billets to a specific temperature, typically above the recrystallization temperature, which makes the steel more malleable and easier to shape. This process is known as hot working. After heating, the steel billets are shaped into the desired form through various techniques such as forging, extrusion, or rolling. These methods allow the steel to be molded into complex shapes, such as dies or molds, which are commonly used in tooling applications. The shaping process ensures that the tooling components have the necessary dimensions, surface finish, and structural integrity to perform their intended function. Once the tooling components are shaped, they may undergo additional heat treatments to further enhance their mechanical properties. Processes like tempering, annealing, or hardening are commonly used to modify the steel's hardness, toughness, and resistance to wear. These treatments increase the tooling's lifespan and improve its performance in demanding manufacturing environments. Overall, steel billets play a crucial role in the manufacturing of tooling by serving as the starting material for shaping tooling components. The high-quality steel used in billets provides the necessary strength and durability required for tooling applications.
