              Description:

              1. Reference Standard
              1: GB 228 metal tensile test method
              2: GB/T 3620.1 titanium and titanium alloy: No. and chemical composition
              3: GB/T3620.2 titanium and titanium alloy processed products chemical composition and composition tolerance
              4: GB 4698 sponge titanium, titanium and titanium alloy chemical analysis method
              2. Technical requirements
              1: The chemical composition of titanium and titanium alloy bars shall comply with the provisions of GB/T 3620.1, and when repeated inspection 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 the hot-processed bar and its allowable deviation should meet the requirements of Table 1.
              3: After hot working, the bar (cold) and cold-rolled, cold-drawn bar diameter tolerances should meet the requirements of Table 2.
              4: The out-of-roundness of the bar after turning (grinding) after hot processing should not be greater than half of its dimensional tolerance.
              5: The length of the indeterminate length of the processed bar is 300-6000mm, and the length of the annealed bar is 300-2000mm. The length of the fixed length or double length should be within the length of the indefinite length. The allowable deviation of the fixed length is +20mm ; The length of the double ruler should also be included in the cut amount of the bar, each cut amount is 5mm. The fixed ruler or double ruler length should be indicated in the contract.

              4:熱加工后經車(磨)光棒材的不圓度應不大于其尺寸公差之半。

              5:加工態棒材的不定尺長度為300-6000mm,退火狀態棒材不定尺長度為300-2000mm,定尺或倍尺長度應在不定尺長度范圍之內.定尺長度允許偏差為+20mm;倍尺長度還應計入棒材的切口量,每一切口量為5mm.定尺或倍尺長度應在合同中注明。
