Grade 5 titanium alloy (UNS R56400) is the most widely used titanium grade. This high-strength alloy can be used at cryogenic temperatures to about 800°F (427°C).
Its Tensile strength (min) can be reached 895Mpa, Ti 6Al 4V, Grade 5 alloy is used in the annealed condition and in the solution treated and Some applications include: compressor blades, discs, and rings for jet engines; airframe and space capsule
components; pressure vessels; rocket engine cases; helicopter rotor hubs; fasteners; critical forgings requiring high strength-toweight ratios.
