René 41 STA is a nickel-base superalloy (Ni-Co-Cr-Mo-W-Al-Ti) in solution heat-treated and aged condition, designed for high-temperature structural applications in jet engines and gas turbines operating up to 1100°F (593°C). The STA condition provides optimized strength and creep resistance through controlled grain structure and precipitation hardening, with excellent bearing strength and fatigue performance in bar, forging, plate, and sheet forms.
