Analysis of common processing technical requirements for titanium rods
1. The chemical composition of titanium and titanium rods shall comply with the provisions of GB/T 3620.1, and when repeated tests are required, the allowable deviation of the chemical composition shall comply with the provisions of GB/T 3620.2.
2. The diameter or side length of the hot-worked bar and its allowable deviation shall comply with the regulations in Table-.
3. After hot processing, the bar is turned (ground) and cold-rolled, and the allowable deviation of the diameter of the cold-drawn bar should meet the industry regulations.
4. The out-of-roundness of the bar that has been turned (ground) after hot processing should not be greater than half of its dimensional tolerance.
5. The indefinite length of the processed titanium bar is 300-6000mm, the indefinite length of the annealed bar is 300-2000mm, and the fixed or multiple length should be within the range of the indefinite length. The allowable deviation of the fixed length is + 20mm; the length of the double length should also be included in the incision amount of the bar, and the amount of each incision is 5mm. The length of the fixed length or the double length should be indicated in the contract.
