Ferrosilicon Supplier Petro Naft: High‑Performance Silicon Alloys for a Decarbonising World
1. Why Ferrosilicon Matters in 2025
Steel and cast‑iron producers rely on ferrosilicon (FeSi)—also known as ferro‑silicon, silicon‑iron alloy or simply Fe‑Si—as an indispensable deoxidiser, alloying agent and inoculant. With the global push toward low‑carbon steel, precision control of oxygen and graphite is more valuable than ever. Demand has followed suit: the worldwide FeSi market reached US $ 11.5 billion in 2023 and is forecast to top US $ 13.6 billion by 2030, a 2.5 % CAGR. grandviewresearch.com
2. Understanding the Alloy
Ferrosilicon is produced in submerged‑arc furnaces from high‑purity quartz, coke and scrap iron. Typical grades—defined chiefly by silicon content—are 45 %, 65 % and 75 % Si, with specialised low‑aluminium and magnesium‑bearing variants (e.g., FeSiMg for ductile iron). FeSi’s strong affinity for oxygen and its ability to nucleate graphite underpin three primary uses:
Deoxidiser in steelmaking—removing dissolved oxygen improves ductility and surface quality. Hensfate Metal
Inoculant / nodulariser in cast iron—promotes “A‑type” graphite, preventing carbides and enhancing machinability. sino-stargroup.com
Reducing agent in specialty ferro‑alloy production—thanks to very low carbon in high‑Si grades.

11. Frequently Asked Questions
| # | Question | Answer |
|---|---|---|
| 1 | What is the difference between FeSi 65 and FeSi 75? | FeSi 75 delivers ~15 % more silicon units, enabling lower alloy addition rates and cleaner metal, whereas FeSi 65 is preferred where strict aluminium limits are unnecessary and cost is the key driver. |
| 2 | How does ferrosilicon improve steel quality? | Silicon forms stable oxides with residual oxygen, preventing nozzle clogging and improving toughness; it also strengthens ferrite through solid solution hardening. |
| 3 | Is ferrosilicon affected by the EU CBAM? | Yes. Although FeSi is not listed explicitly, steel and cast‑iron products made with it are, so importers increasingly request embedded‑carbon data. We supply verified cradle‑to‑gate CO₂e figures for each lot. Taxation and Customs Union |
| 4 | Can FeSi be stored outdoors? | Short exposure is acceptable, but prolonged contact with moisture may oxidise fines. Petro Naft ships in water‑resistant PP bulk bags with PE liners and recommends dry, covered storage. |
| 5 | What alternative names should I search for? | Ferro‑silicon, Fe‑Si, ferrosilicium, silicon‑iron alloy, magnesium ferrosilicon (FeSiMg), nitrided ferrosilicon. |
| 6 | How are prices quoted? | We offer FOB, CFR or DDP terms. Benchmark indices (e.g., Argus FeSi 72 % FOB China) guide base prices, then freight, insurance and certification charges are added transparently. argusmedia.com |
| 7 | Does Petro Naft supply low‑carbon FeSi for speciality alloys? | Absolutely. Our high‑purity furnace programme delivers FeSi 90 % Si with < 0.05 % C—ideal for ultra‑low‑carbon ferro‑manganese production. |
| 8 | What packaging options exist for inoculant grades? | 0–10 mm inoculant is available in 25 kg plastic‑lined sacks or 1 t big‑bags with antistatic liners to prevent dusting. |
| 9 | How do global protectionist measures affect supply? | US and EU trade investigations have tightened availability, making diverse sourcing essential; our multi‑regional footprint cushions clients from sudden tariffs or quotas. S&P Global |
| 10 | Can you provide melt‑shop training? | Yes. Our metallurgists conduct on‑site or virtual seminars covering FeSi handling, best practice dosing curves, and automation integration, typically reducing alloy over‑consumption by 5–10 %. |
