IN-738 Alloy - Preliminary Data (497)

IN-738 is a vacuum-cast, precipitation hardened, nickel-base alloy possessing excellent high temperature creep rupture strength combined with hot corrosion resistance superior to that of many high-strength superalloys of lower chromium content. It provides the gas turbine industry with a cast alloy having good creep strength up to 1700 -1800 F combined with the ability to withstand long-time exposure to the hot corrosive environments occurring in gas turbines. Booklet provides laboratory and field test data, as well as the physical properties of this alloy.
