Where our Ferroniobium (FeNb) ends up.
HSLA and micro-alloyed steels
Niobium refines the grain: pipeline, automotive and high-strength structural steels.
Stabilised stainless steels
Niobium stabilisation of grades such as AISI 347 against intergranular corrosion.
Nickel-based superalloys
Niobium source in charges for alloys such as Inconel 718 (Nb ~5 %).
Construction steels
Micro-alloying for high yield strength and weldability.
Special cast irons
Grain refinement and increased wear resistance.
We collect Ferroniobium (FeNb) in every form.
Granules and lumps
Crushed alloy in furnace lump size, the standard commercial form.
Offcuts and fines
Powders and fine fractions from processing and screening.
Briquettes
Agglomerated fine material for ease of charging.
Drums and big bags
Packaged material from stock surpluses and returns.
