Ingots of vanadium VNM-0, VNM-1, VNM-2
Supplier — AvekGlob Company — offers at reasonable prices from the manufacturer ingots made of vanadium alloys VNM-0, VNM-1 and VNM-2. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Ingots of vanadium alloys ВнМ-0, ВнМ-1 and ВнМ-2 are made from vanadium powder, using methods of powder metallurgy. Due to the high ductility and malleability of vanadium, the ingots after sintering are rolled to obtain the initial blanks of the required width and thickness. 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 vanadium ingots are high corrosion resistance, high elasticity, resistance to high temperatures, increased mechanical strength, and resistance to thermal creep.
Urgency of application
The main application of ingots from the alloys VNM-0, VNM-1 and VNM-2 — billets for the production of parts of industrial and laboratory plants in the glass, chemical industry, for the production of high-temperature ceramics and other applications where chemically aggressive media are constantly used (with the exception of hydrofluoric acid, as well as mixtures of nitric and sulfuric acids). Due to the fact that vanadium actively absorbs neutrons, vanadium ingots can be effectively used also in nuclear power engineering. The springiness of vanadium makes it possible to use vanadium ingots from alloys VNM-0, VNM-1 and VNM-2 in hull structures that constantly experience significant alternating loads.

Assortment and application features
Vanadium ingots VNM-0, VNM-1 and VNM-2 are supplied in cylindrical bars with a diameter of 80 mm to 165 mm and a length of 200… 1500 mm, other parameters are coordinated with the customer.
Vanadium bars can not be used if the operating temperature of the environment reaches 300 ° C or higher: at this temperature, 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.
