L-605 (Haynes 25) is a cobalt-nickel-chromium superalloy solution-treated to provide high strength and excellent creep resistance up to 1200°C (2200°F), suitable for jet engine combustors, afterburners, and high-temperature airframe components. This condition delivers optimal combination of tensile strength, ductility, and thermal fatigue resistance for demanding aerospace applications requiring sustained elevated-temperature performance.
