316Ti is a titanium stabilized version of 316L molybdenum bearing austenitic stainless steel. This results in a better high temperature strength and mechanical strength, but equivalent corrosion resistance to sensitization. It’s not typical free machining grade and there for not recommended. For difficult high speed machining processing.  Sensitization resistance is achieved with the addition of titanium to stabilize the structure of 316Ti  against chromium carbide precipitation, which is the source of the sensitization.


  • Good corrosion and pilling resistance
  • Good resistance at higher temperature
  • Good impact strength on cryogenic temperatures down to minimal -200°C  /-325°F
  • High creep, stress-rupture and tensile strength at elevated temperature

Market applications:

  • Chemical & petrochemical equipment
  • Pharmaceutical
  • Food & Beverage
  • Brewery
  • Shipbuilding
  • Heat exchangers
