Uses. Niobium is used in alloys including stainless steel. It improves the strength of the alloys, particularly at low temperatures. Alloys containing niobium are used in jet engines and rockets, beams and girders for buildings and oil rigs, and oil and gas pipelines. This element also has superconducting properties.iobium is a useful metal in a range of specialist alloys. In amounts as low as 0.1 per cent it has a significant strengthening effect on steel, making it suitable for use in gas pipelines for example. It is also involved in some highly temperature-stable superalloys used for engine parts in the aerospace industry.
