Key Features
On-Demand Annealing – Bars are supplied as-hot rolled or fully annealed per your request; annealing is performed to optimize magnetic softness and machinability.
High Purity Base – Iron content ≥ 99.5% with tight control over C, Si, Mn, and residuals, ideal for alloy additions and magnetic shielding applications.
Tailored Chemistry – Match any standard grade (DT4, YT01, etc.) or adjust elements to meet your proprietary specifications.
Versatile Formats – Round bars in diameters from 10mm to 300mm, cut to your required lengths.

Frequently Asked Questions
Q: Do you always supply annealed bars?
A: No. We supply bars in either as-hot rolled or annealed condition, exactly as you specify. Annealing is performed only when requested, ensuring you get the material state that suits your process.
Q: What purity levels can you achieve?
A: We typically guarantee Fe ≥ 99.5%, and can reach up to 99.8% with careful raw material selection and process control.
Q: How does annealing affect magnetic shielding performance?
A: Annealing removes internal stresses and refines grain structure, which significantly improves magnetic permeability and reduces coercivity – both critical for effective shielding.
Q: Can you supply small quantities for testing?
A: Yes, we welcome sample orders. Our MOQ is flexible to help you validate the material before scaling up.
Q: What documentation do you provide?
A: Each shipment includes a Mill Test Certificate with full chemical analysis. Third-party inspections are also welcome.
