Primarily intended for high temperature applications up to about 1100°C. It provides good microstructural stability, high creep strength and excellent resistance to oxidation and carburization. In a variety of aqueous media, the alloy also has useful resistance to general corrosion, pitting and stress-corrosion cracking. The electrode is optimized for DC+ welding in all positions including fixed pipework qualified in the ASME 5G/6G positions. In addition to welding the parent alloy 617, some authorities specify it in preference to other nickel-base filler metals for welding alloys 800H and 800HT for service above 760°C, alloys 600 and 601 and cast alloys HK40, HP40Nb. It is also suitable for the heat-resistant alloy 601 (usually above 900°C) and dissimilar welds including high carbon heat resistant cast alloys and any combination of those mentioned. Applications include **combustion, pyrolysis, heat treatment and furnace components, flare tips, ducting and gas turbine parts**. Normally no preheat required, interpass temperature generally limited to 150°C maximum.
