Gr2 Titanium Flat Bar correspond to the domestic grade TA2 and are commercial pure titanium profiles. Their UNS number is R50400. They are one of the most widely used types of pure titanium flat bars at present, featuring medium strength, excellent corrosion resistance and good processing performance. The following is a detailed introduction:

The titanium content of Gr2 Titanium Flat Bar is no less than 99%, and the content of impurity elements is strictly controlled. The specific composition complies with standards such as ASTM B348, and the mass fraction ratio is as follows:

Strong compatibility between strength and toughness: In the annealed state, the minimum tensile strength of Gr2 titanium flat bar can reach 345MPa, the minimum yield strength is 275MPa, and the elongation after fracture is no less than 20%. Compared with Gr1 titanium flat bars, it has higher strength and can be adapted to more scenarios with certain load-bearing requirements. Moreover, it can still maintain good mechanical properties in an environment of 100-400 ℃, with a tensile strength of up to 220MPa at 400℃.

Corrosion resistance is nearly "all-round" It has extremely strong resistance to various corrosive media. After being fully immersed in seawater for 30 years, the corrosion rate is less than 0.0005mm/a. In 65% boiling nitric acid, the corrosion rate is less than 0.005mm/a. It can also withstand the erosion of 200g/L sodium hypochlorite at 60℃ and wet chlorine gas at 80℃. It has no resistance to a few media such as oxalic acid and formic acid. There are no problems such as pitting corrosion or stress corrosion cracking.

Excellent processing and welding performance: Industrial titanium rod can be processed through various techniques such as hot and cold rolling, forging, and extrusion, and can also smoothly complete operations such as sawing, drilling, and TIG/MIG welding. No heat treatment is required after welding, and the toughness of the welded area can reach over 85% of the base material. Moreover, appropriate stress release treatment is carried out during processing to prevent material tearing and damage.

Physical properties are suitable for multiple scenarios: With a density of only 4.51g/cm³, it is 40% lighter than steel, effectively reducing the weight of components. It features non-magnetism and low thermal expansion at the same time, will not interfere with electronic devices, and can also adapt to working conditions with large temperature fluctuations.

Marine and chemical engineering fields:

Suitable for manufacturing seawater desalination evaporators, ship propeller components, and deep-sea wellhead connectors; It can also be used in sodium hypochlorite generators, nitric acid storage tanks, ion-exchange membrane electrolytic cells, as well as flanges and supports of chemical pipelines, and can resist the erosion of seawater and various chemical media.

In the medical field:

Due to its biological inertness and biocompatibility, it is often used in artificial joints, dental implants, surgical instruments, and can also be used to manufacture medical bed frames, operating table support systems and other load-bearing medical accessories.

In the fields of aviation and energy:

It can be used as aviation components such as fuselage skins, engine tail nozzles, and hydraulic pipelines; It can also be used in energy equipment such as LNG cryogenic pipelines and nuclear power plant coolers, meeting the usage requirements of both low-temperature and high-temperature working conditions.
