Description
Titanium VT1−2 is used: for the manufacture of semi-finished products (sheets, strips, foils, strips, plates, bars, rods, profiles, tubes, forgings and forged blanks) by the strain, as well as ingots used in the aircraft industry for production of various parts; stamping parts billet heating up to 300−400 °C.
Note
Parts subjected to in-process and final annealing regime: annealing at a temperature of 550−600 °C for 10−15 minutes exposure to 1 mm thickness, and air cooling.
