Abstract

A cast nickel-iron-base alloy component having by weight 12.0 % to 16.5 % Cr, 1.0 % to 2.0 % Al, 2.0 % to 3.0 % Ti, 2.0 % to 3.0 % W, 3.0 to 5.0 % Mo, up to 0.1 % Nb, up to 0.2 % Mn, up to 0.1 % Si, 0.05 % to 0.10 % C, 0.003 to 0.010 % B, 35 % to 37 % Fe, and balance Ni and inevitable impurities. The nickel-iron-base alloy component has a creep rupture life greater than 1000 hours at 25 ksi to 30 ksi at 1400 °F. A method for forming the cast nickel-iron-base alloy component is also disclosed.
