Niobium can be added to stainless steel, so that stainless steel is not easy to crack at high temperature, reduce the heat sensitivity and tempering brittleness of steel, improve the strength, toughness and high temperature creep performance. Niobium plate has small thermal neutron absorption cross section, good corrosion resistance, high temperature strength, and can be used as structural materials for atomic reactors and nuclear fuel packaging materials, but also as a nuclear fuel additive. The superconducting transition temperature of niobium is high and niobium compounds and alloys can be used to produce superconducting materials.
