Overview

INCOLOY® alloy 903 (UNS N19903) is an agehardenable nickel-iron-cobalt alloy whose outstanding characteristics are a constant low coefficient of thermal expansion, a constant modulus of elasticity, and high strength.

Application

INCOLOY® alloy 903‘s characteristics make it an excellent candidate for applications such as rocket-engine thrust chambers, steam-turbine bolts, springs, gage blocks, and ordnance hardware
