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
