Inconel Filler Metal 625 is recommended for gas metal arc and gas tungsten arc welding of nickel base alloys 625 and 601, Incoloy Alloy 802 and 9% nickel steel. Alloy 625 is also useful for various dissimilar joints involving Inconel and Incoloy alloys, carbon steels, low alloy steels and stainless steels. This alloy is useful for jet engine applications requiring excellent stress-rupture strength, oxidation resistance to 1200 degrees F, plus outstanding fatigue strength and cryogenic properties. Many engine applications include ducting systems, combustion systems, thrust reverser assemblies, fuel nozzles, afterburner parts and spray bars.
