Product Introduction
Our ultra-low carbon pure iron billet delivers carbon content as low as 0.002% (20 ppm) – far below the 0.02–0.04% found in standard industrial pure iron. With iron purity ≥99.9% and tight control over sulfur, phosphorus, and trace elements, this billet is engineered for applications where carbon contamination is unacceptable. Available in custom cross-sections (round, square, rectangular) and cut-to-length sizes, hot-rolled with full Mill Test Certificate per batch.
Key Features
| Feature | Benefit |
|---|---|
| Ultra-low carbon (≤0.002%) | Prevents carburization during alloy melting; ensures soft magnetic performance |
| High purity (≥99.9% Fe) | Minimizes trace elements (Si, Mn, P, S, Al, O, N) |
| Low sulfur (≤0.003%) | Reduces hot shortness and improves forgeability |
| Low phosphorus (≤0.005%) | Prevents cold brittleness in finished products |
| Low gas content | O ≤ 0.005%, N ≤ 0.004% – reduces porosity in castings |
| Hot-rolled condition | Dense, uniform grain structure; scales off easily during heating |
| Custom dimensions | Any cross-section and length – made to your specification |
| Full traceability | Mill Test Certificate with every batch, heat number tracking |

Frequently Asked Questions
Q: Do you provide material test reports?
A: Yes – every shipment includes a Mill Test Certificate with full chemical analysis and heat number for full traceability.
Q: Can you customize dimensions and chemistry?
A: Yes – any cross-section, any length, and chemistry adjustments available on request
Q: What does "ultra-low carbon" mean in practice?
A: Carbon ≤0.002% (20 ppm) – roughly 10 times lower than standard industrial pure iron (0.02–0.04%). This prevents unwanted carburization during alloy melting and ensures soft magnetic performance
Q: What is the minimum order quantity?
A: Flexible – from trial quantities to full container loads. Contact us with your requirement
