Titanium Grade 23
Titanium Grade 23 is a variant of Grade 5.
It has lower oxygen, nitrogen and iron. It has better ductility and fracture toughness that Titanium Grade 5.
It is used in medical technology because of its good biocompatibility and excellent fracture toughness and crack propagation behavior. It maintains its good toughness even at low temperatures down to -253 °C. These properties, as well as its low elastic modulus and good fatigue strength are due to the alloy´s relatively low contents of tramp elements such as oxygen and iron (extra-low interstitials). It is excellent in saltwater environments and has an improved ductility.
