About Niobium: It is a rare, soft, malleable, ductile, gray-white metal. It has a body-centered cubic crystalline structure. It must be placed in a protective atmosphere when processed at even moderate temperatures because it tends to react with oxygen, carbon, the halogens, nitrogen, and sulfur. In air, an oxide layer forms over it whose color ...

Niobium (Nb), formerly known as Columbium (Cb), is a metal in group VB of the periodic table with atomic number 41, an atomic weight of 92.91, and a density of 8.4 g/m3. Niobium is similar to Tantalum (Ta), however, it is half the density with a significantly lower unit cost. Niobium is not particularly rare or exotic in that it is the 34th ...

Between 85% to 90% percent of niobium directly goes into producing steel and iron as ferro-niobium. Adding 0.03% to 0.05% of niobium to the steel will increase its yield strength by 30%. Thus, this metal increases steel's strength, toughness, high-temperature oxidation resistance, and corrosion resistance.
