Technical characteristics

Titanium grade gost VT22 alloy relates to a transition type. It possesses high strength-to-density ratio of more than 960 MPa. It was invented in 1965 by VIAM. Later, there were offered modifications of this alloy.

There can be such types of cutting: short transverse, longitudinal, high-altitude, tangential section.

Heat resistance is characterized by the highest stress — creep limit. Under its influence, a material is deformed by a given amount at a given temperature.

Long-term strength is a maximum stress that can disrupt a material after a certain time at a given temperature. The more load duration and the higher temperature are, the less a resistance to rupture is.
