Form This specification covers a titanium alloy in the form of forgings 4.00 inches (101.6 mm) and under in nominal crosssectional thickness and of forging stock of any size. Application These forgings have been used typically for parts in high stress and stress-corrosion-resistant applications requiring higher fracture toughness and allowing lower tensile properties than AMS4984 and AMS4986@ but usage is not limited to such applications.
