Titanium Alloy Bars, Forgings, and Rings 6Al 4V Extra Low Interstitial (ELI) Duplex Annealed, Fracture Toughness
This specification covers a titanium alloy in the form of bars, forgings, flash welded rings, and stock for forging or flash welded rings. These products have been used typically for parts requiring a combination of high tensile strength up to 750 \mDF (399 \mDC) and high fracture toughness, but usage is not limited to such applications.
