Ferro Niobium (FeNb) is a ferroalloy composed of niobium (Nb) and iron (Fe). It is widely used as an alloying element in the steel and superalloy industries to enhance strength, toughness, corrosion resistance, and high-temperature performance.


Chemical Composition:

✅ Niobium (Nb): 60-70%

✅ Iron (Fe): Balance

✅ Silicon (Si): ≤ 2%

✅ Aluminium (Al): ≤ 1.5%

✅ Sulfur (S): ≤ 0.03%

✅ Phosphorus (P): ≤ 0.05%

✅ Titanium (Ti): ≤ 0.5%

Key Features:

✅ Increases Strength & Toughness: Used in high-strength low-alloy (HSLA) steels.

✅ Enhances Corrosion & Heat Resistance: Essential for stainless steels and superalloys.

✅ Refines Grain Structure: Improves weldability and durability in structural applications.

✅ Available in Various Sizes: Typically 10-50mm lumps, granules, or powder form.

Applications:

✅ Steel Industry: Used in pipeline, automotive, and structural steels.

✅ Superalloys & Aerospace: Enhances heat and corrosion resistance in high-performance alloys.

✅ Foundry & Casting: Improves casting properties and wear resistance.

✅ Welding Electrodes: Used in special welding applications.
