Product type
Steel blooms are semi-finished metal products that are typically produced from molten steel. They are characterized by their rectangular or square cross-section and are created through processes such as casting and hot rolling. These blooms serve as a primary raw material for further processing into finished steel products, such as bars, plates, and sheets.
| Material | Carbon steel, alloy steel |
| Typical dimensions | Cross-section from 150 mm to 300 mm |
| Length | Up to 12 meters |
| Weight | Up to 2,500 kg per piece |
| Production method | Continuous casting or ingot casting |
When purchasing steel blooms, buyers should consider the specific grades of steel required for their applications, as well as the desired chemical composition and mechanical properties. It is also important to specify tolerances for dimensions and surface quality. Certifications such as ISO or ASTM standards may be relevant depending on the intended use. Buyers should request quotes based on their required quantities and delivery timelines.
