Titanium bar has good physical and chemical properties, low density, light weight, nonmagnetic, high intensity, complex has good corrosion resistance, it has good mechanical property and welding performance, baoji titanium bars are widely used in chemical equipment, desalination, Marine parts, electroplating industry, etc., the corrosion resistance of titanium is 10 times of general stainless steel and titanium system belongs to the rejection of the lower metal is the human body, so medical titanium rod mechanical parts, widely used in the human body and medical equipment in plant.
1. The chemical composition of titanium and titanium alloy bar materials shall comply with the provisions of GB/T 3620.1, and the allowable deviation of the chemical composition shall comply with the provisions of GB/T 3620.2 when reinspected by the demander.
2. The diameter or side length of hot processed bar and its allowable deviation shall conform to the provisions in table 1.
3, after hot processing by the car (grinding) smooth bar and cold rolling, cold drawing bar diameter deviation should comply with the provisions of table 2.
4. The irregularity of the polished bar after hot processing shall not be greater than half of its dimensional tolerance. 5, the length of the processing state of the bar should be 300-6000mm, the annealed state of the bar is 300-2000mm, the length of the fixed or times the length should be in the range of the length of the indefinite ruler.
