Alloy 901 is an age-hardenable super alloy which contains Titanium
and Aluminium for precipitation hardening and molybdenum for
soild-solution strengthening. Alloy 901 has high yield strength and
creep resistance at temperatures to about 1110°F (600°C). As Alloy
901 has a substantial iron content it enables alloy 901 to combine
strength with good forging characteristics. Alloy 901 is commonly
used for gas turbine engine discs, shafts, rings, casings and
seals.
