It attains its high strength levels through a solution heat treatment followed by a precipitation hardening. Its oxidation resistance remains high for continuous service to 1500°F.
Common applications are jet engine components, bolts, fasteners, afterburners, oil & gas.
Our common stock sizes from = .3125” to 6.000” diameters.
Heat treatment: Heat to 1800 °F ±25 (982 °C), hold at heat for a time commensurate with cross-sectional thickness, and quench in oil or water.
Precipitation heat treatment: Heat to a temperature within the range of 1300 to 1400°F (704 to 760 °C), hold at temperature for a total of not less than 16 hours, and cool at a rate equivalent to cooling in air.
Hardness requirement = 241 to 341 HB.
