03 · Typical applications

Where our Ferroniobium (FeNb) ends up.

→ 01

HSLA and micro-alloyed steels

Niobium refines the grain: pipeline, automotive and high-strength structural steels.

→ 02

Stabilised stainless steels

Niobium stabilisation of grades such as AISI 347 against intergranular corrosion.

→ 03

Nickel-based superalloys

Niobium source in charges for alloys such as Inconel 718 (Nb ~5 %).

→ 04

Construction steels

Micro-alloying for high yield strength and weldability.

→ 05

Special cast irons

Grain refinement and increased wear resistance.
