E - longitudinal direction of cut samples; P - transverse; H - height, T - tangential.

Heat resistance is characterized by the creep limit - the greatest stress under the action of which the material at a given temperature deforms by a given amount. The index through the fraction is the deformation and the time in which this deformation occurs.

Heat resistance of titanium bar VT22

Bar Thickness (mm) Heat treatment t°C Creep strength (0.2/100)
VT22 25 Annealing 300° 764
VT22 25 Annealing 350° 402
VT22 80 Quenching + aging 250° 890
VT22 80 Hardening+aging 300° 880

The long-term strength is the greatest stress that fractures the material at a given temperature, after a certain time. Naturally, the higher the temperature and the longer the load duration, the lower the tensile strength.
