Alloy 242 is an age hardenable nickel-molybdenum-chromium alloy which
derives strength from a log-range ordering reaction upon aging. It has
tensile and creep strength properties up to 1300°F which are as much as
double for solid solution strengthened alloys, but with high ductility
in the aged condition. The thermal expansion characteristics of alloy
242 are much lower than those for most other alloys, and it has very
good oxidation resistance up to 1500°F.
