Introduction

INCONEL 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.

Character

l Good mechanical properties at high temperatures

l Good formability

l Good oxidation resistance

Application

l Oil and gas production

l Gas turbine engines

l Nuclear engineering
