UNS N19909 Alloy 909, Incoloy 909 Quick facts & description: UNS N19909, also known as Alloy 909, Incoloy 909 , has a constant low coefficient of thermal expansion, constant modulus of elasticity, along with an high strength. Low expansion characteristics gives chance of greater power and improved fuel efficiency, while high strength increase strength/weight ratio giving chance to reduce weight. Thanks to this Alloy 909 finds application in: land based gas turbines and aerospace jet engines, into shrouds, shafts, casings, vane rings, defense & military is thrust chambers of rocket engines, ordnance, springs, steam turbines bolts. Main chemistry: Ni 35-40% ; Nb 4.3-5.2% ; Ti 1.3-1.8% ; Co 12-16% ;Fe balance Main fields of application: Aerospace, Energy
