VT22 titanium pipe, wire

VT22 titanium pipe, wire

Titanium alloy VT22 brand belongs to the transitional type which has a minimum durability of more than 960 MPa. It was developed in 1965 in VIAM. It was later proposed modification of this alloy — ВТ22ч, ВТ22И, ВТ22М.

P is transverse the cutting direction of the samples; — high-rise, D — longitudinal, T — Tangenziale.

Heat resistance is characterized by the highest voltage — creep strength, under whose influence the material is deformed by a given amount at a given temperature.

Long-term strength is the maximum stress, destroys the material after a certain time at a given temperature. Note: the longer the load and the higher the temperature, the tensile strength is less.
