Technical Data Sheet
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.
