Precision titanium rod technical requirements

Now, with industrial, chemical development and integration progress, some features excellent metal element, is used to make the appropriate industrial parts, and high-precision titanium rod is one of them, and huge development potential.
What is a high-precision titanium rod it?
It is made of titanium metal element precision bar, with its low density, high mechanical strength, easy processing, so many people are now processing it.
Then we have what technical precision Titanium round rod requests?
1, titanium and titanium alloy bars of chemical composition shall conform to GB / T3620.1, the deviation is not too large;
2, thermal processing bar diameter or side length and tolerances shall comply with the provisions of Table I;
3, thermal processing by car (mill) light bar and cold-rolled, cold-drawn bar diameter tolerances shall comply with the provisions of Table II;
4, after the thermal processing by car (grinding) roundness light bars should not half its size tolerances;
5, the processing state bar does not cut lengths strict rules.
