Nickel 722 is a nickel-chromium alloy strengthened by the addition titanium and aluminum. The alloy is age-hardenable by heat treatment. It also has the capacity to remain effective at extremely high temperatures. Inconel 722 can withstand the stress caused by several types of acids, which has made it a common metal in the chemical industry.
NICKEL 722 is used for gas turbine structural components, such as turbine section frames. The alloy is useful where oxidation resistance and high temperature strength are of major importance.
