What Is The Classification Of Titanium Tubing?
Apr 25, 2024
1,Alpha titanium alloy
It is a single-phase alloy composed of α-phase solid solution, whether at the general temperature or at higher temperatures of practical applications, are α-phase, stable organization, wear resistance is higher than pure titanium, strong oxidation resistance. Under the temperature of 500℃~600℃, it still maintains its strength and creep resistance, but it cannot be strengthened by heat treatment, and its room temperature strength is not high.
2,Beta titanium alloy
It is a single-phase alloy composed of β-phase solid solution, which has high strength without heat treatment, and the alloy is further strengthened after quenching and aging, and the room-temperature strength can be up to 1372-1666MPa; however, it has poor thermal stability, and it is not suitable to be used at high temperatures.
3,Alpha + beta titanium alloy
It is a dual-phase alloy with good overall performance, good organizational stability, good toughness, plasticity and high-temperature deformation properties, can be better hot pressure processing, quenching, aging to make the alloy strengthened. The strength after heat treatment is about 50% to 100% higher than the annealed state; high high-temperature strength, can work for a long time at a temperature of 400℃ to 500℃, and its thermal stability is second to that of α titanium alloy.
