Semi-finished Titanium Bolts after Forging

In the video,there are Tens of thousands of seminfinished titanium bolts.The finish looks like grey white color,they are all generated after Acid and alkali washed after forging. It is a processing for titanium bolts production.For the normal Torx socket,they are usually forged out by mold when doing head forging.After forging the head blank is formed and then CNC turning the head types. The head forging can save material cost and increase head strength of the titanium bolts. For titanium Grade 5,usually they are heat forged but not cold forged.When doing cold forging,it will generate cracks.But when do heat forging,the finish of titanium will generate a thick oxide layer.So we have to remove it by Acid and alkali.
