Steel billet :
Steel billet(ingot) by cogging or breakdown of semi-finished products, is the raw material of all kinds of steel mill. Billet section of square, round, flat, rectangular
and abnormity of several kinds of, mainly related to the shape of rolled products.
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 common sizes and shapes of steel billets?
- To cater to the diverse needs of different industries, steel billets are typically manufactured in various sizes and shapes. The most common sizes range from 100mm to 200mm in width and 100mm to 300mm in height. However, it should be noted that these dimensions can vary based on the specific requirements of the end-user or the steel manufacturer. Regarding shapes, rectangular and square shapes are commonly produced. Rectangular billets have flat and smooth surfaces with four right angles, while square billets have equal sides with four right angles as well. These shapes are preferred because they facilitate easier handling, transportation, and further processing of the steel billets. Furthermore, steel billets can also be produced in non-traditional shapes such as round, hexagonal, or octagonal, depending on the intended application. These unique geometries are often utilized in specialized industries like automotive or aerospace manufacturing to meet specific design requirements. It is important to mention that the sizes and shapes of steel billets can vary across different regions and industries, as each may have their own specific standards and preferences. Therefore, manufacturers and end-users should communicate and align their requirements to ensure the production of steel billets that meet their respective needs.
- Q: What are the main alloying elements used in steel billet production?
- Steel billet production utilizes various alloying elements, such as carbon, manganese, silicon, and chromium. The primary alloying element, carbon, plays a crucial role in augmenting the steel's strength and hardness. Meanwhile, manganese is incorporated to enhance the steel's toughness and hardenability. Silicon is introduced to fortify the steel against corrosion and oxidation. Lastly, chromium is employed to heighten the steel's hardness, corrosion resistance, and wear resistance. Throughout the production process, these alloying elements are meticulously regulated and added to the steel to attain the desired properties and attributes in the ultimate steel billets.
- Q: What are the different surface treatments for improved fatigue resistance in steel billets?
- Some of the different surface treatments that can improve fatigue resistance in steel billets include shot peening, nitriding, and induction hardening. Shot peening involves bombarding the surface of the billets with small steel shots, which creates compressive stresses that help to increase fatigue strength. Nitriding is a process where the steel billets are exposed to nitrogen gas at high temperatures, forming a hard nitride layer on the surface which improves both hardness and fatigue resistance. Induction hardening involves heating the surface of the billets using high-frequency currents and then rapidly quenching it, resulting in a hardened surface layer that enhances fatigue resistance.
- Q: What are the different surface treatments applied to stainless steel billets?
- Stainless steel billets can undergo several surface treatments to enhance their appearance and improve their resistance to corrosion. Some commonly used surface treatments include: 1. Pickling: By immersing the billets in an acid bath, like nitric or hydrofluoric acid, any scale or oxide layers formed during the manufacturing process can be removed. Pickling restores the stainless steel's original finish and provides a clean and smooth surface. 2. Passivation: This chemical process is employed to boost the corrosion resistance of stainless steel. By immersing the billets in an oxidizing solution, usually a nitric acid bath, any embedded iron or contaminants are eliminated from the surface. Passivation creates a thin oxide layer on the stainless steel surface, which aids in preventing corrosion and maintaining the integrity of the material. 3. Electropolishing: This electrochemical process involves removing a thin layer of material from the billet's surface. By passing an electric current through the billets while they are submerged in an electrolyte solution, the surface becomes smoother and any defects or impurities are eliminated. Electropolishing not only enhances the appearance of stainless steel but also improves its corrosion resistance and facilitates cleaning. 4. Grinding and polishing: These mechanical processes utilize abrasive materials to eliminate imperfections or irregularities from the stainless steel billets' surface. Grinding is achieved using a coarse abrasive wheel, while polishing involves progressively finer abrasives to achieve a smooth and reflective surface. These processes can produce various finishes, ranging from a brushed or satin finish to a mirror-like polished finish. These different surface treatments can be utilized individually or in combination to achieve the desired appearance and performance characteristics for stainless steel billets in diverse applications.
