UNS R56410 (Titanium alloy 10V-2Fe-3Al)

Short Introduction:

Titanium alloy 10V-2Fe-3Al is a near beta alloy developed as a high strength forging alloy. This grade provides the best combination of strength and toughness of the commercially available titanium alloys. Its strength permits about a 27% weight savings when compared to Ti-6Al-4V. At the 180 ksi tensile strength level, the K1cvalue is 40 ksi-in ½ minimum. Solution treated and aged material possesses excellent resistance to stress corrosion cracking, typically K1scc being greater than 0.8 K1c. Solution treated material should not be subject to long term exposure in the 500-800°F range. This could result in high strength but low ductility.
