Titanium Transage 129, Triplex Heat Treat 760/650/425°C
Categories: Metal; Nonferrous Metal; Titanium Alloy; Beta Titanium Alloy

Material Notes: This alloy has very good fatigue resistance, which is enhanced by an alpha-beta anneal at 650ºC before aging at 425-540ºC.


  • Martensitic alloy
  • High hardenability
  • Heat treatable
  • Good fatigue properties
  • Good fracture properties
  • Suitable for hot-working and cold-forming

See other heat treatments for this alloy as well as entries for Transage 134 and 175.
