Supplier — AvekGlob company — offers at reasonable prices from the manufacturer bars and a circle of alloys VnP-1 and VnP-2. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Vanadium alloys VnP-1 and VnP-2 are made from vanadium powder, using the methods of powder metallurgy. Due to the high ductility and malleability of vanadium, the semi-finished products after sintering are subjected to rolling or extruding to obtain the initial blanks of the required diameters. The technical conditions for the production of these alloys are determined by the regulatory requirements of TU 48−4-272−73. The characteristic features of rolled alloys VnP-1 and VnP-2 are high corrosion resistance, high elasticity, resistance to high temperatures, increased mechanical strength, resistance to thermal creep .

Urgency of application

The main application of VNP-1 and VnP-2 alloys is industrial and laboratory installations in the glass, chemical industry, the production of high-temperature ceramics and other applications where chemically aggressive media are used (except for hydrofluoric acid, as well as mixtures of nitric and sulfuric acids). Due to the fact that vanadium actively absorbs neutrons, these alloys can be effectively used also in nuclear power engineering. The springiness of the materials makes it possible to use them in designs that constantly experience significant alternating stresses.

Assortment and application features

The circle and bar of VnP-1 and VnP-2 vanadium alloys are supplied in the form of bars of cylindrical shape with a diameter from 10 to 160 mm, length from 200 to 1500 mm.

Alloys can not be used if the operating temperature of the environment reaches 300 ^° C or higher: at this temperature, vanadium becomes brittle. Weldability of alloys is satisfactory, the method of welding with a tungsten non-consumable electrode in a helium or argon medium is used.

Supplier — AvekGlob Company — offers to buy a circle or rod made of VnP-1 and VnP-2 grades in a wide range of diameters and lengths. 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.
