Description

Active Austenite Finish Temperature of Nitinol Tube

The austenite finish temperature of the finished tube (active Af) with outer diameter in the range of 0.3 to 3.0 mm (0.012 to 0.12 in.) shall be measured on representative full round tube sample(s) using the bend and free recovery method described in Test Method ASTM F 2082-15.

  • Superelastic properties are measured per Test Method F2516 at room temperature (22+/-2℃)
  • Applicable Standard: ASTM F2633

 

Surface Finish of Nitinol Tube

  • Outer surface: Black oxide or Center-less Ground.
  • Inner surface: Etched or oxide.
