Ferroniobium FeNb60

Ferroniobium is a ferroalloy containing about 60% Nb (or Nb + Ta), 10-12.5% Si, 2-6% Al, 3-8% Ti (the rest is Fe and impurities ); melted in an electric furnace aluminothermic method from pyrochlore concentrate or technical niobium pentoxide. Ferroniobium is used in the smelting of structural steel and heat-resistant alloys.

Alloying alloy of iron and niobium (the sum of niobium and tantalum). Ferroniobium is introduced into stainless chromium-nickel steels to prevent their intergranular corrosion and destruction and into other types of steel to improve their properties.
