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.

The alloy's characteristics make it an excellent candidate for applications such as rocket-engine thrust chambers, steam-turbine bolts, springs, gage blocks, and ordnance hardware.

Mechanical Properties

INCOLOY alloy 903 has high mechanical properties at room temperature and retains much of its strength up to around 1200°F (650°C). As indicated by the impact strength, no deleterious phases were present in the alloy. All properties are reported for age-hardened material. Stress-rupture properties of the alloy are governed by thermomechanical processing. Typical stress to produce rupture in 100 h of agehardened material at 1200°F (650°C) is 85 ksi (586 MPa). Room-temperature plane strain fracture toughness (KIC) of agehardened alloy 903 is 100.6 ksi • in (111.36 MPa • m) (average of three tests).

Corrosion Resistance

Testing was conducted for 500 h at 1000°F (540°C), 1100°F (595°C), and 1200°F (650°C). The specimens were alternately exposed to the test temperature for 15 min and cooled in air for 5 min. Because alloy 903 contains no chromium, oxidation resistance may become a consideration for some hightemperature applications. In such cases, protective coatings may be desirable.
