Wire, rod, pipe, bar made of niobium
Niobium is greyish-silvery lustrous metal that is designated in periodic table of chemical elements as Nb. Its atomic weight is 93.986. Boiling temperature is 5015°К. Melting point is 2741°К. Niobium has body-centered cubic crystal lattice, a — 0.3294 millimicrons of type α-Fe.

Nowadays, niobium manufacture is growing fast. It is connected with a lucky combination of such properties such as refractory quality, low thermal-neutron capture cross-section, gettering property, capability to form super-conducting and heat-resisting alloys, corrosion resistance, perfect processability in cold and hot state, weldability, low work of electron liberation. The main application spheres of niobium are rocket engineering, air-craft and space techniques, radiotechniques, electronics, industrial chemistry, and nuclear energetics.
Niobium is quite expensive metal. Metallic niobium fume irritates eyes, skin. It is flammable material. Its separate joints are very toxic. MPC of Nb constitutes 0.01 mg/l. In the event of its entry into human body, niobium can provoke neuritis with further pamplegia.
niobium and its alloys are applied in manufacturing the parts of rockets, air-planes; coverages of uranium and plutonium boilers (melting points of NbC carbide is 3480°С), containers for liquid metal. Applicable heating agents in nuclear reactors — liquid sodium and potassium circulate through tubes. Niobium possesses low artificial (induced) radioactivity. That is why it fits to storage the wastes of radioactive elements. It is broadly used for manufacture of electrolytic capacitors as well as for «hot» fitting of powerful electronic tubes (anodes, cathodes, grids).
Resistant to corrosion devices for chemical industry are also made out of niobium alloys. Non-ferrous metals and even uranium are alloyed with a help of this metal. Niobium is utilized in superconducting — cryotron components of the computing machines. It is also used in accelerating structures of the hadron collider.

Steel pipe alloyed with niobium possess high strength and corrosion resistance. Packed pipes can be transported with any type of transport. During transportation, they must be protected from moisture, chemically active elements, mechanical deformations.
