The performance and application of titanium forgings!

Titanium forgings have high strength, low density, good mechanical properties, good toughness and corrosion resistance. In addition, titanium forgings have poor technological performance, are not easy to cut, are easy to absorb impurities such as hydrogen, oxygen, nitrogen, carbon, etc. during hot processing, and have poor wear resistance and complex production processes. The industrial production of titanium began in 1948, and with the development of the aviation industry, the titanium industry is growing at an average annual rate of about 8%. At present, the global annual output of it has reached more than 40,000 tons, and there are nearly 30 types of it. The most widely used titanium forgings are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).

Titanium forgings are mainly used in the manufacture of compressor components for aircraft engines, followed by structural parts for rockets, missiles and high-speed aircraft. In the mid-1960s, titanium and its alloys were used in general industries such as making electrodes for the electrolysis industry, condensers in power stations, heaters in oil refining and desalination, and in environmental pollution control devices. Titanium and titanium alloys have emerged as corrosion-resistant structural materials. In addition, it is used in the production of hydrogen storage materials and shape memory alloys.

Standard: National Standard GB/T 16598-1996

American Standard: ASTM B381

Material: TA0, TA1, TA2, TA3, TC4

Delivery state: Annealed state (M) Hot working state (R) Cold working state (Y) (annealing, ultrasonic flaw detection)

Packing: carton or wooden box

Surface treatment: car light, chamfering

Surface quality: The surface roughness Ra of the two end faces should not be greater than 3.2m (subject to the requirements of ultrasonic flaw detection), and the surface roughness Ra of the inner and outer sides should not be greater than 12.5m (Ra should not be greater than 3.2 m during cylindrical ultrasonic flaw detection). Circumferential surface required), the chamfering radius is 5 ~ 15mm. There should be no visible defects such as cracks, folds, double skins, etc. on the surface of the product. Local surface defects can be removed by grinding, the cleaning depth should not exceed the dimensional tolerance, and the minimum allowable size should be guaranteed. The ratio of the cleaning depth to the width of the two end faces should not exceed 1: 6, the inner and outer sides should not exceed 1: 10, and the outer grinding should be carried out in the axial direction.

Well, the above is all about the performance and application of titanium forgings. I hope you like it!
