Ferroniobium FeNb70 Description
Ferroniobium is mainly used for smelting high-temperature (heat-resistant) alloys, stainless steel and high-strength low-alloy steel.
Niobium in stainless steel and heat-resistant steel combines with the carbon in the steel to form stable niobium carbide.
Evenly distributed on the grain boundaries of steel, it prevents the grain growth of steel at high temperatures, refines the structure of steel, and improves the strength, toughness and creep properties of steel.

The chemical affinity between niobium and carbon is much greater than that between chromium and carbon. Therefore, when niobium is present in stainless steel, it can prevent the precipitation of chromium carbide at the grain boundaries of the steel, thereby improving the corrosion resistance of the steel.
Niobium and nitrogen in steel form stable niobium nitride, which improves the corrosion resistance of the steel surface.
Niobium in the steel and oxygen generate stable niobium oxide, forming a niobium oxide film on the surface of the steel, which can prevent oxygen from diffusing into the interior and act as an antioxidant.
Adding Nb0.015% to 0.05% to carbon steel can refine the structure and make the steel have good formability and welding performance.
Niobium has a strong inhibitory effect on the austenite recrystallization of steel, allowing the steel to effectively control rolling at higher temperatures, and the strengthening and toughening effect of controlled rolling is very significant.
Therefore, the amount of niobium used as a micro-alloying element in carbon steel has greatly increased.
Niobium plays the role of solid solution strengthening and carbide precipitation strengthening in high temperature alloys, improving the yield strength and surface stability of high temperature alloys.
The weight of niobium is one of the lighter refractory metals and is one of the factors that contributes to the extensive use of high-temperature alloys.
