one. Titanium rod overview
Passive titanium rods and titanium alloy rods are new structural materials. Because titanium has high melting point, small specific gravity, high specific strength, good toughness, fatigue resistance, acid and alkali corrosion resistance, low thermal conductivity, high and low temperature resistance, Features such as low stress under the conditions of rapid cold and rapid heat. It is used in high-tech fields such as aviation and aerospace, and is continuously promoted to industries such as chemical, petroleum, electric power, desalination, construction, and daily necessities.
two. Common grades of titanium rods
National standard number: TA1, TA2, TA3, TA7, TA9, TA10, TA15, TA18, TC4, TC4ELI, TC6, TC9, TC10, TC11

1. The chemical composition of titanium and titanium alloy bars should meet the requirements of GB/T 3620.1. When repeated inspections are required, the allowable deviation of the chemical composition should meet the requirements of GB/T 3620.2.
2. The diameter or side length of the hot processed bar and its allowable deviation should meet the corresponding regulations.
3. After hot processing, after turning (polishing) the bar and cold rolling, the allowable deviation of the diameter of the cold drawn bar shall comply with the industry regulations.
4. The out-of-roundness of the turned (polished) bar after hot working should not be more than half of its dimensional tolerance.
