Ti-6Al-4V STA is a solution heat-treated and aged (STA) condition of the titanium alloy Ti-6Al-4V, providing improved strength and creep resistance compared to annealed conditions through precipitation hardening, with typical yield strengths in the 140–160 ksi range. This condition is widely used in aerospace applications including jet engine compressor blades, landing gear, and airframe components requiring high specific strength, fatigue resistance, and reliable performance up to approximately 300°C.
