Ferro Niobium is a ferroalloy produced by reducing niobium pentoxide with iron using aluminothermic or electric furnace processes. It is mainly used as a micro-alloying element in steel making to significantly improve strength, toughness, weldability, and grain refinement at very low addition levels.
Ferro Niobium is essential for producing HSLA steel, structural steel, automotive steel, pipeline steel, and stainless steel, suitable for domestic use and import–export trade.
