A steel ingot is a large, solid block of steel cast from molten metal. Ingots serve as raw materials for further processing into rolled bars, sheets, and other steel products. They are used in forging, rolling, and extrusion processes to manufacture high-strength components for construction, automotive, and industrial applications.
- Ingot Size Range: 3.5”x4.5”,4.5”x5.5”,6.5”x7.5”,8.5”x 9.5”, 10”x12”
Steel Ingots Specification
| Size |
Typically weighs 1–5 tons, with dimensions varying (e.g., 2–3 meters long, 0.3–1 meter
wide).
|
| Chemical Composition | Primarily carbon (0.05%-2%), manganese, silicon, and low sulfur and phosphorus. |
| Mechanical Properties | Tensile strength (400–800 MPa), yield strength (250–700 MPa), hardness (170–250 HB). |
| Surface | Rough surface from casting, requiring further processing. |
| Grades | Can include carbon, alloy, stainless, and tool steel ingots. |
| Casting Process | Usually made by ingot casting or continuous casting. |
Key Features of Steel Ingots
| Feature | Description |
|---|---|
| Size and Shape | Steel ingots are usually large, rectangular or square blocks, with sizes depending on the requirements of the intended use. They can be several tons in weight and can vary in dimensions. |
| High Purity | Steel ingots typically have high purity, with minimal impurities, which ensures better quality in the final products made from them. The purity can be adjusted based on the alloy composition and the intended application. |
| Homogeneity | A key feature of steel ingots is their uniformity in composition. Modern ingot casting techniques aim to reduce segregation of elements to ensure consistent quality throughout the ingot. |
| Strength and Durability | Steel ingots are generally known for their strength and durability, though the specific mechanical properties can vary depending on the alloy composition (carbon steel, alloy steel, etc.). |
| Malleability and Workability | Steel ingots are produced in a manner that makes them suitable for further processing, such as forging, rolling, or casting, to create various steel products like bars, beams, or sheets. |
