AMS 5225 UNS N09902 Iron-Nickel Alloy Strip Solution Heat Treated,
Cold Rolled, 50% Reduction
N09902 strip has been used typically for diaphragms, leaf springs,
and helical springs, requiring a precipitation-hardenable alloy
with a temperature coefficient of modulus of elasticity of -20 to
+20 x 10-6 per degree Fahrenheit from -50 to +150 °F (-36 to +36 x
10-6 per degree Celsius from -46 to +66 °C) after suitable heat
treatment, but usage is not limited to such applications.
