Incoloy MA956

INCOLOY® alloy MA956 (UNS S67956), first developed as an aerospace super alloy and now used in a range of industrial applications, combines excellent strength and fabricability with outstanding resistance to prolonged exposure up to 1300°C (2400°F). Its exceptional properties result from the mechanical alloying process by which it is made; a process which allows a fine distribution of yttrium oxide particles to be incorporated into a highly corrosion-resistant Fe-Cr-Al alloy.
