Technical Requirements For Titanium Bar

The α alloy contains a certain amount of elements that stabilize the α phase,Titanium Bar and it is mainly composed of the α phase in equilibrium. Alpha alloy has a small specific gravity, good thermal strength,Titanium Bar good weldability and excellent corrosion resistance. The disadvantage is that it has low room temperature strength and is usually used as a heat-resistant and corrosion-resistant material. Alpha alloys can generally be divided into full alpha alloys (TA7), near alpha alloys (Ti-8Al-1Mo-1V) and alpha alloys with a small amount of compounds (Ti-2.5Cu).

Technical requirements: The chemical composition of titanium and titanium alloy bars should meet the requirements of GB/T 3620.1. When repeated inspections are required,Titanium Bar the allowable deviation of the chemical composition should meet the requirements of GB/T 3620.2. The diameter or side length of the hot processed bar and its allowable deviation shall meet the requirements of Table 1. After hot processing,Titanium Bar after turning (polishing) the bar and cold rolling, the allowable deviation of the diameter of the cold drawn bar shall meet the requirements of Table 2. The out-of-roundness of the turned (polished) bar after hot working should not be more than half of its dimensional tolerance.

The indefinite length of the processed bar is 300-6000mm, the indefinite length of the annealed bar is 300-2000mm,Titanium Bar and the fixed or multiple length should be within the range of indefinite length. The allowable deviation of the fixed length is +20mm;Titanium Bar times The length of the ruler shall also be included in the cut amount of the bar,Titanium Bar and the amount of each cut is 5mm. The fixed-length or double-length length shall be indicated in the contract.
