Wire vanadium

Wire vanadium

Supplier — AvekGlob company — offers vanadium wire at a reasonable price from the manufacturer in a wide range of diameters. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Vanadium is a silver-gray transition metal with relatively good plastic and forging properties. Vanadium is paramagnetic. The technical conditions for the production of vanadium wire meet the requirements of TU 48−4-374 — 76.

Urgency of application

The main application of vanadium wire is measuring elements, arrow indicators and other details controlling the processing conditions for chemically aggressive media (except for hydrofluoric acid, as well as a mixture of nitric and sulfuric acids). Vanadium wire is used in installations of chemical, petrochemical and gas industries. Due to the fact that vanadium actively absorbs neutrons, wire from this metal is also used in nuclear power engineering.

Chemical composition

In the production of vanadium wire, 99.5% pure metal is used. The main impurities are nitrogen, oxygen, cadmium, bismuth. To remove them, high-temperature annealing is used. The final composition of the profile in question contains:

  • Iron — 0,04… 0,35%;
  • Silicon — 0.003… 0.25%;
  • Aluminum — 0,01… 0,35%;
  • Sulfur — 0.08… 0.2%;
  • Carbon is 0.2… 1.7%.

Physical and mechanical properties

  • Density, kg / m 3 — 6110;
  • Melting point, 0 С — 1910;
  • Specific heat capacity, J / kggrad — 249.5;
  • Modulus of elasticity, GPa — 127.6;
  • Coefficient of thermal conductivity at room temperature, W / megade — 30,8;
  • The limit of temporary resistance, MPa — 800;
  • Limit of plasticity, MPa — 125.5;
  • Relative elongation at tension,% — 30;
  • Hardness for Brinell, HB, not more than 165.

Assortment and application features

Since vanadium is plastic enough, the technology of multiple cold drawing is used to produce wire from this metal. Vanadium wire is supplied in the following assortment — a diameter of 0.1 to 3 mm when winding onto reels or reels.

Vanadium wire is not used if the operating temperature of the environment reaches 300 ° C or higher: at these temperatures, the metal becomes brittle. Weldability of vanadium is satisfactory: the method of welding with a tungsten non-consumable electrode in helium or argon is used.

Supplier — AvekGlob Company — offers to buy vanadium wire in a variety of diameters. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
