ВТ16 pipe, wire
Brand titanium ВТ16 developed в1963 G. Vilom especially for the production of parts. Because of the fairly large percentage of β-stabilizers contains a lot of β-phase in the annealed condition of 35 — 40%. In the annealed condition the toughness of the alloy is not very large (about 875 MPa). Aging and tempering to achieve strength over 1400 MPa.

Advantages and application of titanium alloy ВТ16
|Easily deformed in hot and cold phases. The alloy is well welded using any type of welding.||Has high resistance to cut, low sensitivity to stress concentrators. Can easily withstand the load with the bias. Has a good effect of aging and hardening.||840−880°||And various threaded fasteners dia. 40 mm, which work at the temperature. up to 300 °C.|

Heat resistance is characterized by the highest voltage — creep strength, under whose action the material is deformed by a given amount at a given temperature.
At all temperature operating conditions, the plasticity, strength properties of deformed semi-finished products of titanium is much higher than casting from the same brands. The strength properties of materials change depending on the mode of heat treatment and resulting microstructure (basket weave, globular, lamellar). The greatest strength shows a globular structure. The strength basket is 87−98% of the globular, the lamellar strength is 75−85%. The influence of microstructure on the fatigue resistance depend on the asymmetry factor of R — cycles.
Hire brand ВТ16 has a high specific strength, corrosion resistance, namagnichennosti; its strength is not inferior to steel but lighter by almost half. ВТ16 is heat resistance, low thermal conductivity, easy stamped and forged. For corrosion resistance superior to stainless steel. Disadvantage is high labor intensity, energy intensity of the production of titanium. But despite his high cost, it is widely popular, because have a winning combination of performance. Semi brand ВТ16 in the hot state is well deformed. At temperatures up to 850 °C are the basic operations of stamping. Alloy welded satisfactorily, you’ll be casting good properties.
Manufacture of threaded fasteners with a diameter up to 40 mm continuously operated at t° up to 300 °C, and at temperatures up to 130 °C — with unlimited resource.
