This page explains how Steel Slabs is classified within Basic Metal Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
Semi-finished steel products with rectangular cross-sections produced through continuous casting or ingot casting processes.
Technical details and manufacturing context for Steel Slabs
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Carbon ContentRequired | 0.05–0.25 % | 0.05–0.25 — For carbon steel slabs; higher carbon increases strength but reduces weldability. For carbon steel slabs; higher carbon increases strength but reduces weldability.ASTM A36/A36M |
| LengthRequired | 4000–12000 mm | 4000–12000 — Custom lengths available; longer slabs reduce handling but require larger transport. Custom lengths available; longer slabs reduce handling but require larger transport.EN 10079 |
| Surface Temperature | 800–1100 °C | 800–1100 — Hot charging temperature; below 800°C risks cracking, above 1100°C causes scale formation. Hot charging temperature; below 800°C risks cracking, above 1100°C causes scale formation. |
| ThicknessRequired | 150–300 mm | 150–300 — Thicker slabs for heavy plate; thinner for strip rolling. Thicker slabs for heavy plate; thinner for strip rolling.EN 10079 |
| WeightRequired | 15–60 t | 15–60 — Single slab weight; depends on width, thickness, and length. Single slab weight; depends on width, thickness, and length. |
| WidthRequired | 800–2200 mm | 800–2200 — Width range for flat rolling; wider slabs reduce edge trimming. Width range for flat rolling; wider slabs reduce edge trimming.EN 10079 |
| Casting temperature | 1520–1560 °C | 1520–1560 °C — Outside this window: Below 1520°C: risk of nozzle blockage; above 1560°C: increased gas porosity and breakouts. Outside this window: Below 1520°C: risk of nozzle blockage; above 1560°C: increased gas porosity and breakouts. |
| Casting speed | 0.8–1.6 m/min | 0.8–1.6 m/min — Outside this window: Too slow: surface cracks; too fast: breakout risk and internal cracks. Outside this window: Too slow: surface cracks; too fast: breakout risk and internal cracks. |
| Secondary cooling water flow | 0.5–1.5 L/kg | 0.5–1.5 L/kg — Outside this window: Insufficient cooling: bulging and cracks; excessive cooling: thermal shock and surface defects. Outside this window: Insufficient cooling: bulging and cracks; excessive cooling: thermal shock and surface defects. |
| Mold oscillation frequency | 100–200 strokes/min | 100–200 strokes/min — Outside this window: Low frequency: sticking; high frequency: oscillation marks and surface defects. Outside this window: Low frequency: sticking; high frequency: oscillation marks and surface defects. |
| Straightening temperature | 900–1050 °C | 900–1050 °C — Outside this window: Below 900°C: cracks; above 1050°C: reduced strength and distortion. Outside this window: Below 900°C: cracks; above 1050°C: reduced strength and distortion. |

Steel slabs typically have thicknesses ranging from 150 to 300 mm, widths from 800 to 2200 mm, and lengths from 4000 to 12000 mm, as per EN 10079. However, these values are reference ranges and must be confirmed for specific applications.
Steel slabs can be made from carbon steel, alloy steel, or stainless steel. For carbon steel, the carbon content typically ranges from 0.05% to 0.25%, affecting strength and weldability.
Common standards include ASTM A36/A36M for carbon steel, EN 10079 for dimensions, and ISO 9001 for quality management. These are procurement references; compliance must be verified with the supplier.
Key parameters include casting temperature (1520–1560 °C), casting speed (0.8–1.6 m/min), secondary cooling water flow (0.5–1.5 L/kg), mold oscillation frequency (100–200 strokes/min), and straightening temperature (900–1050 °C). These affect quality and must be controlled.
