Understanding Steel Billets
What is a Steel Billet?
A steel billet is a rectangular or square cross-section metal ingot produced by pouring molten steel into molds and allowing it to solidify. It is a semi-finished product that can be further processed into various shapes, such as bars, rods, and other forms, through processes like rolling, forging, or extrusion.
Key Properties of Steel Billets
- High Strength: Steel billets are known for their high strength and durability, making them ideal for applications that require structural integrity.
- Versatility: They can be used in a wide range of metal casting processes, including sand casting, die casting, and investment casting.
- Thermal Conductivity: Steel billets have good thermal conductivity, which is essential for maintaining consistent temperatures during the casting process.
- Machinability: Steel billets can be easily machined into various shapes and sizes, allowing for customization and precision in the final product.
