This page explains how Steel Ingots 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 cast into standardized shapes for further processing.
Technical details and manufacturing context for Steel Ingots
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Alloy GradeRequired | ASTM A36, A572 Gr.50, 1045, 4140, 316L, 304L grade | ASTM A36, A572 Gr.50, 1045, 4140, 316L, 304L — Specify grade per application; each grade has distinct mechanical properties.ASTM A36 · ASTM A572 |
| Carbon ContentRequired | 0.05–1.20 % | 0.05–1.20 — Low carbon (<0.15%) for formability, high carbon (>0.5%) for hardness.ASTM E1019 |
| DimensionsRequired | 100x100x500–500x500x2000 mm | 100x100x500 to 500x500x2000 — Standard ingot sizes; custom sizes available on request.ASTM A29 |
| Surface Temperature | 20–60 °C | 20–60 — Temperature at delivery; higher temperatures indicate insufficient cooling. |
| WeightRequired | 0.5–10 ton | 0.5–10 — Typical ingot weight; larger ingots may require special handling. |
| Tolerance on Dimensions | ±5 mm | ±5 — Tighter tolerances available at extra cost.ASTM A29 |
| Surface Quality | No cracks, scabs, or laps; surface defects ≤2 mm depth visual | No cracks, scabs, or laps; surface defects ≤2 mm depth — Inspect per ASTM A29; defects may be removed by chipping or grinding.ASTM A29 |
| Internal Soundness | Ultrasonic testing per ASTM A388; max indication size 3 mm | Ultrasonic testing per ASTM A388; max indication size 3 mm — For critical applications; specify if required.ASTM A388 |
| Chemical Composition Limits | P ≤0.04, S ≤0.05, Cu ≤0.20 % | P ≤0.04, S ≤0.05, Cu ≤0.20 — Residual elements controlled to avoid hot shortness and surface defects.ASTM A29 |
| Delivery Condition | As-cast, annealed, or normalized condition | As-cast, annealed, or normalized — Specify heat treatment if required for subsequent processing. |
| Pouring temperature | 1520–1560 °C | 1520–1560 °C — Outside this window: Too low: cold shuts and misruns; too high: excessive oxidation and gas pickup. |
| Mold preheat temperature | 80–120 °C | 80–120 °C — Outside this window: Below 80°C: thermal shock and cracking; above 120°C: mold distortion and sticking. |
| Cooling rate after solidification | 0.5–2.0 °C/min | 0.5–2.0 °C/min — Outside this window: Too fast: internal stresses and cracking; too slow: segregation and coarse grain. |
| Storage temperature before dispatch | 20–60 °C | 20–60 °C — Outside this window: Above 60°C: risk of oxidation and scale; below 20°C: condensation and rusting. |

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Steel ingots are intermediate products used as input material for rolling, forging, or extrusion processes to produce finished steel products such as bars, plates, and structural sections.
Common grades include ASTM A36, A572 Gr.50, 1045, 4140, 316L, and 304L. Each grade has distinct mechanical properties; the appropriate grade depends on the application.
Standard dimensions range from 100x100x500 mm to 500x500x2000 mm, with tolerances of ±5 mm. Ingot weight typically ranges from 0.5 to 10 tons.
Quality is verified through surface inspection per ASTM A29, ultrasonic testing per ASTM A388 for internal soundness, and chemical analysis per ASTM E1019. Always confirm specific requirements with the supplier.
