about Inconel X-750:
INCONEL® alloy X-750 (UNS N07750/W. Nr. 2.4669) is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to 1300°F. Although much of the effect of precipitation hardening is lost with increasing temperature over 1300°F, heat-treated material has useful strength up to 1800°F. Alloy X-750 also has excellent properties down to cryogenic termperatures.

INConELalloy X-750 wire is process-annealed at 1900°F. about 40% cold reduction before re-annealing is preferable. Hot heading or hot upsetting is best done at 1800° to 2000°F. Generally, the wire is heated by induction or resistance and then fed into the die for forming.
