Niobium Flange Manufacturers, Suppliers & Stockist in India – Various Types of Niobium Flanges at Low Price, Best Quality & Fast Delivery in India and Worldwide!
- We are manufacturing Niobium flanges in various sizes and material standards. We can also manufacture your specific flange requirements in short delivery time. Metallica is India’s leading exporter and manufacturer of Niobium flanges, with monthly production and sales of over 2000 tons. Most of our production of carbon steel flange and stainless steel flange exported out of India to over 45 countries.
- The major grades of Niobium Flanges are Unalloyed Niobium R04210, Nb-10W-10Hf, UNS Grade R04261—Niobium + 1 % Zirconium (Nb1Zr), UNS Grade R04295—Niobium + 10% Hf+1 % Ti (Nb10Hf1Ti); Reactor Grade – Unalloyed Niobium R04200, UNS Grade R04261—Niobium + 1 % Zirconium ( Nb1Zr); Superconducting – Nb-50Ti.
- A steel flange (forged, cut from plate, or rolled) comes in a variety of shapes and sizes to suit different applications. A flange is usually in the shape of a round disc and is used to connect two pipes together or to connect a pipe to a pressure vessel, valve, pump, integral flanged assembly or other component. A flange comes with holes for bolts around the rim. Bolts are used to connect two flanges which are typically attached to pipe ends with a gasket in between.
- Niobium Flange temperature and pressure tolerances are dependent on the rating. We specialize in producing high purity uniform shaped Niobium Flanges. We also offer custom flanges with annealed or hard tempers and will meet most of the common Milspec or ASTM standards.
- Niobium Flanges are available in multiple shapes, as welding neck (the pipe is welded to the collar of the flange), threaded (the pipe is screwed on the flange), socket weld (fillet welds connections), lap joint (for connections using stub ends), slip on, etc. A Niobium flange can also be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.
- The ASME B16.5 and ASME B16.47 specifications cover US standard pipe flanges, the EN 1092-1 specification covers European steel flanges.
- A Niobium flange can be produced and designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

What is Niobium?
Niobium, also known as columbium, is a chemical element with the symbol Nb and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal. Pure niobium has a Mohs hardness rating similar to that of pure titanium, and it has similar ductility to iron. Niobium oxidizes in the earth’s atmosphere very slowly, hence its application in jewelry as a hypoallergenic alternative to nickel. Niobium is a rare, soft, malleable, ductile, gray-white metal. Niobium exhibits similar but slightly lower resistance against chemicals corrosive to tantalum. It must be placed in a protective atmosphere when processed at even moderate temperatures because it tends to react with oxygen, carbon, the halogens, nitrogen, and sulfur. The metal is inert to acids, even to aqua regia at room temperatures, but is attacked by hot, concentrated acids, and especially by alkalis and oxidizing agents. However, 90% of its total demand arises from the production of high-strength low-alloy steels, whereas rolled niobium–based products account for 4% and superalloys and compounds (oxides and chemicals) account for 3% each.

Prices for Niobium Flanges
Prices for Niobium Flanges are directly co related to prices of the raw materials such as iron ore, metal scrap, chromium, nickel and various other alloying elements. The production cost of heat resistant stainless steel and nickel alloy plates is high as they contain high amount of nickel and chromium. Meanwhile, mild steel material is among the lowest cost steel available, followed by carbon steel, 400 series stainless steels, aluminium, alloy steel, and 300 series stainless steel. Special alloys such as titanium, Inconel, Monel and Hastelloy cost very high as the nickel, chromium and moly content is very high.
