ABSTRACT:
A method of manufacturing nickel-iron-chromium alloys for use with recuperators. A combination of intermediate annealing, cold working and final annealing results in an alloy having a greater yield strength than a corresponding solution annealed material. The resultant alloy exhibits an isotropic structure and has high corrosion resistance, a low coefficient of expansion and high levels of ductility and strength.
