Ferroniobium

Ferroniobium is niobium based master alloy produced aluminothermically from niobium pentoxide and iron oxide, used as alloying additive in heat resistant and stainless steels to improve their corrosion resistance, plasticity and welding properties. Niobium addition to construction steels prevents welded joint from corrosion.

Vacuum-grade Ferroniobium is used for superalloys additions in turbine blade applications in jet engines and land-based turbines, inconel family of alloys, superalloys.
