Use & Application
Designed to match the
composition of alloy 625,
widely used for the
resistance to general corrosion, pitting, crevice and
stress corrosion cracking in severe chloride media.
These properties are due to high levels of
Cr, Mo and Nb, which also raise
strength to the highest amongst standard nickel-base
alloys. Useful properties from –269°C to above 1000°C.
Also suitable for welding
heat resisting alloys including Inconel 601 , Incoloy 800/800H, or
combinations of these with other alloys for furnace
equipment, petrochemical and power generation
plants. Some other applications include:
overmatching corrosion-resistant welds in alloy 825,
Hastelloys G and G3, alloy 28, 904L, 6%Mo superaustenitic
stainless 254SMo, and also overlays on
pumps, valves and shafts, often in offshore and marine
environments where high pitting resistance (PRE = 50)
and tolerance to dilution are essential.
Welds in high strength ferrous alloys including
cryogenic 9% nickel steels and for reclamation of
dies where rapid work-hardening and toughness are
required. No preheat required and maximum interpass of
250°C. For superaustenitic alloys the
interpass temperature should be controlled to a
maximum of 100°C.
