Form
This specification covers a titanium alloy in the forms of investment castings having four grades of permissible discontinuities.
Application
These castings have been used typically for parts of intricate design requiring a combination of good strength-to-weight ratio, creep and fatigue properties, and corrosion resistance up to 750°F (399°C), but usage is not limited to such applications.
