At Beifang Alloy, we specialize in producing high-purity ferrosilicon (FeSi) that enhances steel’s corrosion resistance—critical for marine, chemical, and infrastructure applications. This guide covers procurement needs, market trends, buying strategies, and supplier selection to help you secure the best FeSi for durable, rust-resistant steel.
| Parameter | Standard Grade | Premium Grade |
|---|---|---|
| Si Content | 65-75% | 72-75% |
| Carbon (C) | ≤0.1% | ≤0.05% |
| Aluminum (Al) | ≤1.5% | ≤0.5% |
| Phosphorus (P) | ≤0.04% | ≤0.02% |
✔ Forms Protective SiO₂ Layer – Shields steel from oxidation and acidic environments
✔ Reduces Sulfide Inclusions – Minimizes pitting corrosion in harsh conditions
✔ Enhances Chromium Efficiency – Boosts performance in stainless steel alloys
✔ Low Aluminum Content – Al >0.5% accelerates corrosion in chloride-rich environments
✔ Batch Consistency – ±0.3% Si variation to maintain uniform protection
✔ Traceability – Mill test reports (MTRs) for critical applications
🔹 Marine & Offshore Growth – Global shipbuilding orders up 22% YoY (needing corrosion-resistant steel)
🔹 Chemical Plant Expansions – Acid-resistant steel demand rising in Asia (+18% CAGR)
🔹 Green Steel Shift – Low-carbon FeSi reduces CO₂ emissions in corrosion-resistant alloys
✔ Certifications – ISO 9001, NACE MR0175 for sour service
✔ Testing Capabilities – XRF for Si%, ICP-MS for trace impurities
✔ Sustainability – CBAM-compliant carbon reporting (<2.5t CO₂/MT)
