Performance Analysis of TA Series Corrugated Expansion Joint

TA2 is an industrial titanium with a single alpha phase. Industrial pure titanium is divided into three grades: TA1, TA2 and TA3 according to its impurity content. The interstitial impurity elements of these three kinds of industrial pure titanium gradually increase, so its mechanical strength and hardness also gradually increase, but the plasticity and toughness decrease accordingly.

TA3 is industrial titanium. The industrial pure titanium commonly used in industry is TA2 because of its moderate corrosion resistance and comprehensive mechanical properties. TA3 can be used when high wear resistance and strength are required. TA1 can be used when better molding properties are required.

TA4, α-type titanium alloy, this kind of alloy is in α-type single-phase state at room temperature and service temperature, and cannot be strengthened by heat treatment (annealing is the only form of heat treatment), and mainly depends on solid solution strengthening. The tensile strength of TA4 is slightly higher than that of industrial pure titanium, and it can be used as a structural material in the medium strength range. Mainly used as welding wire in China.

Industrial pure titanium has better comprehensive properties and excellent corrosion resistance, making it an indispensable structural material for many industrial parts. As a bio-implant material, it has been widely used clinically since the 1960s. Among all the commonly used implant metal materials, titanium has good biocompatibility, and because its density and elasticity are close to human bones, it is non-magnetic.

1. Impurity content: TA1, TA2, TA3 sequentially increase the impurity content,

2. Mechanical strength: TA1, TA2, TA3 increase in turn,

3. Hardness: TA1, TA2, TA3 increase in turn,

4. Plastic toughness: TA1, TA2, TA3 decrease sequentially.

The low temperature titanium alloy represented by TC4 (Ti-6Al-4V), its strength increases with the decrease of temperature, but the plasticity changes little. It maintains good ductility and toughness at low temperatures of -196-253°C, avoids cold brittleness of metals, and is an ideal material for cryogenic containers, storage boxes and other equipment.
