About Niobium Flange

Niobium FlangeNiobium flange standards include ASA/ANSI/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). Flange temperature and pressure tolerances are dependent on the rating. American Elements specializes in producing high purity uniform shaped Niobium Flanges. American Elements offers custom flanges with annealed or hard tempers and will meet most of the common Milspec or ASTM standards. Niobium flanges are circular with external ridges and varying threaded holes. In addition to standard alloys, American Elements also specializes in corrosion resistant alloys, high temperature applications, and custom shapes and forms, including custom hole drill locations and threading. American Elements also produces Niobium as rod, ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Flanges are often used to connect pipes or steam cylinders. Most flanges have external ridges with circular holes so screws can provide extra safety and strength.

See more Niobium products. Niobium (atomic symbol: Nb, atomic number: 41) is a Block D, Group 5, Period 5 element with an atomic weight of 92.90638. Niobium Bohr ModelThe number of electrons in each of niobium's shells is 2, 8, 18, 12, 1 and its electron configuration is [Kr] 4d4 5s1. The niobium atom has a radius of 146 pm and a Van der Waals radius of 207 pm. Niobium was discovered by Charles Hatchett in 1801 and first isolated by Christian Wilhelm Blomstrand in 1864. In its elemental form, niobium has a gray metallic appearance. Niobium has the largest magnetic penetration depth of any element and is one of three elemental type-II superconductors (Elemental Niobiumalong with vanadium and technetium). Niobium is found in the minerals pyrochlore, its main commercial source, and columbite. The word Niobium originates from Niobe, daughter of mythical Greek king Tantalus.
