5. skills requirement
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 processing, the rods are cold-rolled (ground) and
cold-rolled. The allowable deviation of the diameter of the
cold-drawn rods should comply with industry regulations.
4). The out-of-roundness of the bar after turning (grinding) after
hot processing should be no more 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
range of the length of the indefinite length. ; 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.
