characteristic
Titanium series BT, grades 6, 6C, 6C belongs to the group of α + β-alloys. Manufacture of plate, sheet, foil of BT series is standardized by GOST 19807−74, and also OST 90013−81. The alloy VT6 contains 4.5% vanadium and 6% Al, and the alloy BT6C 4% vanadium and 5% Al. Aluminum hardens the α + β phase, and vanadium stabilizes the β phase and inhibits the formation of α-2 superstructure in the α phase. Heat treatment of the alloy increases the strength to 20% without loss of ductility.

Long-term strength is characterized by the maximum stress, which at a given temperature destroys the material, after a certain period of time.

Heat resistance is characterized by the greatest stress — the creep limit, under whose influence the material is deformed by a given value at a given temperature.
Advantages
Sheet rolling brand VTCH, VT6 has sufficient heat resistance, so it can be used in a wide range of temperatures. Unique strength properties of the material are due to its balanced chemical composition and additional heat treatment. Non-magnetism, high resistance to the influence of aggressive gas-like environments (so-called gas corrosion), against the background of sufficient technological ability, determined the scope of the rolled products of the brand VTCH, VT6.
application of
Fragments of equipment for chemical engineering, structural elements working in contact with sea or chlorinated water, industrial condensate. Heat resistance, high specific strength serves as a basis for structural elements of aircraft engineering: fuselage, chassis, aileron mechanisms, fastening components, production of gas turbine engine components. Due to the corrosion resistance, heat exchange equipment, ship equipment parts, chemical reactors and containers are manufactured.
