- Other Elements, each—0.0 wt % to 0.1 wt %;
- Other Elements, total—0.0 wt % to 0.4 wt %;
- and
- Titanium—Balance.
An enhanced strength Ti-6Al-4V Grade 23+ alloy composition having less than or equal to 0.10 wt % Oxygen, having the same or greater strength as a Ti-6Al-4V Grade 23 alloy, wherein the Ti-6Al-4V Grade 23+ alloy results from controlling the following combination of elements in the Ti-6Al-4V Grade 23 alloy:
- Aluminum;
- Iron;
- Nitrogen;
- and
- Carbon.
A method of increasing the strength or reducing the Oxygen content of Ti-6Al-4V Grade 23 titanium alloy to produce Ti-6Al-4V Grade 23+ titanium alloy, the method comprising adjusting the following combination of elements in the Ti-6Al-4V Grade 23 alloy:
- Aluminum;
- Iron;
- Nitrogen;
- and
- Carbon.
