Product Overview
Unlike standard carbon steel, our ultra-low carbon pure iron billet is specifically engineered for applications where carbon contamination is unacceptable. With carbon levels as low as 0.002% (20 ppm), our billets deliver:
Excellent magnetic permeability – ideal for electromagnetic cores and shielding
Clean alloy melting – no unwanted carburization in superalloys or precision alloys
Consistent mechanical properties – high ductility and low hardness for cold forming
As the actual manufacturer, we control every step from electrolytic iron production to billet casting and hot rolling. You get factory-direct pricing, full traceability, and the ability to customize billet size, shape, and chemical composition to your exact requirements.
Key Features
| Feature | Benefit |
|---|---|
| Ultra-low carbon (≤0.002%) | Prevents carburization in alloy melting; ensures soft magnetic performance |
| High purity (≥99.9%) | Minimizes trace elements (Si, Mn, P, S, Al, O, N) |
| Customizable dimensions | Square billets: 60–200 mm; rectangular or round billets available |
| Hot rolled surface | Descaled and shot‑blasted for clean surface, ready for forging or rolling |
| Low gas content | O ≤ 0.005%, N ≤ 0.004% – reduces porosity in castings |
| Factory direct | Competitive pricing, short lead times, direct technical support |
Why Choose Our Ultra-Low-Carbon Pure Iron Ingots?
✅ Ultra-low carbon, suitable for critical applications
Standard industrial iron has a carbon content of 0.02–0.08%. Our iron ingots have a carbon content of ≤0.002%, making them ideal for the following applications:
Superalloys
Precision investment casting-pure melting, no porosity
Soft magnetic cores-low coercivity, high magnetic permeability
✅ Consistent Purity Across Batches
Every batch is analyzed using ICP-OES and combustion infrared spectroscopy. We provide a Certificate of Analysis (COA) with each shipment, detailing the actual content of C, Si, Mn, P, S, Al, O, N, and other trace elements.
✅ Custom Sizes and Shapes
We produce billets in a variety of cross-sections:
Square: 60×60 mm, 80×80 mm, 100×100 mm, 150×150 mm, 200×200 mm
Rectangular: Customized according to customer drawings
Round: Diameter range from 18 mm to 300 mm
Length: Typically 2–6 meters, or cut to your specifications.

Frequently Asked Questions
Q: Can you supply billets cut to specific lengths?
A: Yes. We can cut billets to any length from 100 mm to 6 meters. For shorter pieces, we recommend ordering cut‑to‑length to avoid material waste.
Q: Do you provide magnetic property testing?
A: Yes. For soft magnetic applications, we can test coercivity (Hc), permeability (μ), and saturation induction (Bs) per GB/T 13012 or ASTM A773 after customer‑performed annealing.
Q: How does this billet compare to DT4 or DT4C electrical iron?
A: Our ultra‑low carbon billet meets or exceeds DT4C chemical requirements. After proper annealing, it achieves magnetic properties comparable to DT4C (Hc ≤ 48 A/m, μᵢ ≥ 10,000). It can be used as a direct substitute.
Q: What is your MOQ for ultra‑low carbon billets?
A:MOQ is 5 tons for standard sizes. Sample orders (100‑500 kg) are available for evaluation – please contact us to discuss.
Q: How does factory‑direct pricing benefit me?
A: You avoid distributor markups, typically saving 15‑25%. You also get faster lead times and direct technical support for composition adjustments or dimensional changes.
