Alloy 901
Introduction
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.
Typical Uses and Applications
Alloy 901 is commonly used for gas turbine engine discs, shafts, rings, casings and seals.
