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.

- Q: What are the different heat treatment processes used for steel billets?
- Steel billets undergo various heat treatment processes, each with its own distinct purpose and resulting in different mechanical properties. These processes encompass annealing, normalizing, quenching, tempering, and case hardening. Annealing involves heating the steel billets to a specific temperature and gradually cooling them to enhance ductility and soften the material. This process mitigates internal stresses and promotes uniformity in the steel's microstructure. Normalizing entails heating the steel billets beyond the critical point and allowing them to cool in ambient air. This process improves the grain structure and mechanical properties like strength and toughness. It also reduces residual stresses and enhances the steel's machinability. Quenching is a rapid cooling technique that immerses heated steel billets in a quenching medium, such as water or oil, to achieve high hardness. The resulting material is brittle, necessitating subsequent tempering to reduce brittleness and improve toughness. Tempering involves reheating quenched steel billets to a specific temperature and then allowing them to cool slowly. This process relieves residual stresses and enhances material toughness and ductility. It also reduces the hardness attained during quenching, resulting in a balanced combination of strength and toughness. Case hardening selectively hardens the surface layer of steel billets while maintaining a softer and more ductile core. This is accomplished by introducing carbon or nitrogen into the material's surface layer through carburizing or nitriding processes. Case hardening improves surface hardness and wear resistance, making it suitable for applications that require high surface hardness. Overall, these diverse heat treatment processes for steel billets yield a range of mechanical properties, enabling customization based on specific application requirements. Each process possesses unique advantages and limitations, with selection dependent on factors such as desired mechanical properties, steel grade, and intended application.
