Technical requirements for titanium alloy rods

1. The chemical composition of titanium and titanium alloy rods shall comply with the provisions of GB/T 3620.1. When repeated testing is 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 hot-processed rods and their allowable deviations should comply with the provisions of Table 1.

3. After hot processing, the bar is turned (ground) and cold rolled. The allowable diameter deviation of the cold drawn bar should comply with the provisions of Table 2.

4. The out-of-roundness of the turned (ground) bar after thermal processing should not be greater than half of its dimensional tolerance.

5. The variable length of the processed bar is 300-6000mm, and the variable length of the annealed bar is 300-2000mm. The fixed length or double length should be within the range of the indefinite length. The allowable deviation of the fixed length is +20mm ;The double length should also be included in the incision amount of the bar, and the amount of each incision is 5mm. The fixed length or double length should be specified in the contract.
