Inconel 706 is a nickel-iron-chromium precipitation-hardening superalloy with columbium and titanium additions, designed for high-strength applications in aerospace gas turbines and fasteners operating to approximately 1300°F (704°C). The heat-treated condition provides excellent tensile strength and bearing properties with good ductility, making it suitable for critical rotating and structural components requiring sustained elevated-temperature performance with reliable stress-rupture resistance.
