Identification markings on steel billets for traceability, quality control, and inventory management in metal manufacturing.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Data Encoding | Alphanumeric, 2D Data Matrix, QR, barcode (Code 128, Code 39) | Encoding options for traceability data.ISO/IEC 16022 |
| Marking Depth | 0.1–0.5 mm (dot peen), 0.05–0.2 mm (laser), 0.2–1.0 mm (stamping) mm | Depth varies by method; deeper for impact, shallower for laser. |
| Contrast Ratio | ≥ 3:1 (for machine readability) | Measured under specified lighting; critical for automated reading.ISO/IEC 15415 |
| Character Height | 5–20 mm (typical), 2–5 mm (laser micro-marking) mm | Height depends on readability distance and method. |
| Permanence Rating | Permanent (survives 1200°C, abrasion, chemical exposure) | Must remain legible through downstream processing. |
| Readability Distance | 0.5–5 m (human), 0.1–1 m (machine vision) m | Distance for reliable reading; depends on character height and contrast. |
| Temperature Resistance | Up to 1200°C (continuous), 1400°C (short-term) °C | Marking must survive high-temperature processing without degradation. |
| Surface temperature | 20–1200°C | Outside this window: Below 20°C: paint may not cure; above 1200°C: marking may degrade or substrate damage. |
| Surface condition | Clean, dry, scale-free (for paint/laser); slight scale acceptable for stamping | Outside this window: Oil, moisture, or heavy scale reduces adhesion and readability. |
| Production speed | Up to 120 billets/hour (automated marking) | Outside this window: Higher speeds may cause incomplete marks or misalignment. |
| Ambient environment | Temperature: -10 to 50°C; humidity: 5–95% non-condensing | Outside this window: Extreme humidity or temperature affects paint viscosity and laser performance. |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Manufacturer profiles associated with Identification Markings.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Standard markings include heat number, grade code, dimensions, production date, manufacturer ID, and sometimes customer order references. This follows ISO 10474 and similar standards for global consistency.
Methods include robotic stamping, laser marking, dot-peen engraving, and high-temperature paint stenciling. Selection depends on temperature, required permanence, and production speed, with automated systems ensuring consistent application.
Properly applied markings using approved materials and methods do not affect metallurgical properties. However, excessive depth or inappropriate materials can create stress concentrations or contamination risks, requiring controlled application parameters.
