VT20 titanium pipe, wire
General characteristics
Titanium alloy VT20 developed in 1965 by Vinom as a more durable alloy sheet in comparison with the brand VT5−1. Its hardening, the improvement in properties is due to alloying with aluminium, zirconium, molybdenum, vanadium. This alloy has high heat resistance. In hot conditions, it is easily deformed and welded using any type of welding, including other titanium alloys, and the strength of the weld joint is similar to the strength of the base metal. VT20 is lightweight, its density is 4.45 g/cm3, and melting point is 980 — 1020 °C.

| VT20 | 950° | 800° | 980° — 1020° | 700° — 850° | 700° — 800° |
The heat resistance of VT20 and other pseudo α-alloys, strongly dependent on the cooling rate after heat treatment. The greatest resistance is achieved by cooling with an intermediate rate between the furnace and water cooling.
Disadvantages
High content of aluminum reduces the technological ductility of the alloy when processing by pressure, in contrast to the same alloy grade FROM-4 .

Use
VT20 is intended for the production of welded assemblies that work at t° up to 450 °C — in the manufacture of body parts of aircraft wing skin, parts of GTE. VT20 — pipe are widely demanded by shipbuilding, petrochemical industry, space technology, in the production of oil, gas well drilling. She copes with many tasks, due to the heat resistance, strength, endurance in a hostile environment. Reliability and durability, resistance to corrosion, no sediment of organic salts on the walls throughout the operation, allows the tubes to fully preserve their quality for a long period of time.
