Characteristics of BT20 alloy

Titanium alloy VT20 (pseudo α-alloy: Ti-6,5Al-1Mo-1V-2Zr) was developed by VIAM in 1965. As compared to VT5-1 it is a stronger sheet alloy. The alloy hardening is achieved by balanced alloying with aluminum, zirconium, molybdenum, vanadium. The composition is characterized by heat resistance, it is well deformed in the hot state and welded by any means (including other titanium alloys), the strength of the welded joint is equal to the strength of the base metal. It is a light alloy, its density is 4.45 g/cm³, melting point is 980 - 1020 °C.

The heat resistance of pseudo α-alloys, in particular BT20, depends significantly on the rate of cooling after heat treatment. The greatest heat resistance gives cooling with some intermediate rate between cooling with the furnace and in water.

Disadvantages

Because of the high aluminum content the plasticity of the alloy when machining pressure is lower than that of the similar grade OT-4.

Application

The manufacture of parts and welded units, working long hours at t ° up to 450 ° C - for the wing liner, airframe parts, parts of combustion engines. Tube grade BT20 is in demand in shipbuilding, industrial chemistry, space technology, in oil and gas production. Thanks to the heat resistance, corrosion resistance strength in corrosive media, reliability, absence of deposition of salts and organic compounds on the walls during the entire service life, these pipes maintain all their qualities declared at the beginning of the period of operation for a long time.
