Metrode Nimrod-617KS description: Nimrod 617KS is 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 carburisation. In a variety of aqueous media, the alloy also has useful resistance to general corrosion, pitting and stress-corrosion cracking. The electrode is optimised 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.
