Ferroniobium (FeNb 65% Standard & Vacuum Grade)

Standard 65% Nb and vacuum-grade FeNb for HSLA line-pipe steels, automotive sheet and aerospace superalloys

Ferroniobium under HS 7202.93 is the master alloy that micro-alloys high-strength steel. It is bought on contained niobium—the benchmark is 65.0% to 70.0% Nb—and on its deleterious residuals: silicon (≤ 3.0%), aluminium (≤ 1.5% to 2.0%), carbon (≤ 0.15% to 0.20%), phosphorus (≤ 0.20%), sulphur (≤ 0.10%), and tantalum (≤ 0.50% standard, ≤ 0.10% vacuum grade). Adding just 0.03% to 0.05% niobium to molten carbon steel doubles its yield strength through micro-structural grain refinement and carbonitride precipitate hardening. This grain-refining potency makes FeNb indispensable for high-strength low-alloy (HSLA) automotive sheet, seismic structural beams, offshore wind tower monopiles, and API 5L X70/X80 oil and gas line pipe, where it provides high strength with superior low-temperature impact toughness and weldability without requiring costly post-weld heat treatment. For nickel-based superalloys (such as Inconel 718 containing ~5% Nb for aircraft jet turbine discs), melt shops consume low-tantalum, low-gas vacuum-grade ferroniobium.

The global supply architecture is exceptionally concentrated: Brazil accounts for approximately 80% to 85% of total world production, anchored by Companhia Brasileira de Metalurgia e Mineração (CBMM) operating the world's premier pyrochlore deposit in Araxá, Minas Gerais (dispatched via the Port of Santos), alongside CMOC Brasil's Catalão mine. Canada provides the primary non-Brazilian supply line via Magris Performance Materials' Niobec underground mine in Saint-Honoré, Quebec, shipped through the Port of Saguenay and Port of Montreal. UN Comtrade export declarations under HS 7202.93 reflect over USD 2.2 billion in annual trade, with Brazil exporting over 75,000 MT primarily to China, the European Union, the United States, Japan, and South Korea. CBIL is a commodity brokerage company and brokers standard metallurgical and vacuum-grade ferroniobium from Brazilian and Canadian producer and trading house allocations directly to integrated blast furnace/BOF and EAF steelmakers, pipe mills, and superalloy forgers. Parcels move in 250 kg steel drums strapped on pallets or 1,000 kg heavy-duty woven FIBC bags in 20-ft ocean containers (20 to 24 MT/box) on FOB, CFR, and CIF terms. Offers stand against certified manufacturer certificates of analysis per lot or independent SGS/Alfred H Knight verification of Nb, Ta, Si, Al, C, P, S, and 10–50 mm sizing. Fastmarkets publishes weekly reference assessments for ferroniobium 65% Nb in-whs dp Rotterdam and US, which settle term formulas. Send the required niobium grade, tantalum ceiling, sizing, and discharge port to work the parcel against current terminal positions.
