Nimonic 901 (UNS N09901)
Nimonic 901 (UNS N09901) is an age-hardenable Ni-Fe-Cr superalloy with significant additions of molybdenum, titanium and aluminum. The alloying route for this high performance material may include combinations of vacuum induction melting, vacuum arc remelting and electroslag remelting, according to the final application and the customer’s specification. Typically, the alloy is used for gas turbine engine discs, shafts, rings, casings and seals with a maximum service temperature of around 600°C (1100°F).
