NIOBIUM

Flanges

Stainless India is the leading niobium products SUPPLIERS and provider in India. Besides domestic market, Stainless India exports about 40 percent of its productivity overseas, including various of niobium wire, niobium rod, niobium plate, niobium, niobium tubes, and all kinds of niobium machining parts. The Niobium machining parts is the most competitive product of Stainless India. We can produce various niobium screw, nuts, elbows, flanges, valves and so on. The wire products has been exported to more than 40 countries and regions including United States, Canada, Germany, Brazil, Australia, Japan

Niobium is a shiny, white, soft, ductile and paramagnetic metal, which takes on a bluish tinge when exposed to air at room temperatures for extended periods. It has a low density in comparison to other refractory metals, and it is corrosion resistant, exhibits superconductivity properties, and forms dielectric oxide layers. These properties, especially the superconductivity, are strongly dependent on the purity of the niobium metal. When very pure, it is comparatively soft and ductile, but impurities make it harder.
