Technical requirements

  1. The chemical composition of titanium and titanium alloy rods shall comply with the provisions of GB/T3620.1. When repeated inspections 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-processed bar and its allowable deviation should meet the requirements in Table 1.
  3. The allowable deviation of the diameter of the cold-drawn bar should comply with the provisions in Table 2 after the hot-working (grinding) bar and cold-rolled.
  4. The out-of-roundness of the turned (polished) bar after thermal processing should not exceed half of its dimensional tolerance.
  5. The indeterminate length of the processed bar is 300-6000mm, and the indeterminate length of the annealed bar is 300-2000mm. The fixed length or double length should be within the range of the indeterminate 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 each incision is 5mm. The fixed length or double length should be specified in the contract.
