EN/ISO 14172: ENi6625 NiCr22Mo9Nb
DIN 1736: EL NiCr20Mo9Nb
FEATURES & APPLICATIONS |
For joining and cladding most nickel alloys, stainless steels, and carbon steels. Excellent for oxidation and corrosion resistant applications.
- Inconel 625 electrode that performs on AC current as well as DC current.
- Rare version of this “Super Alloy” that works perfectly on small AC machines.
- Welds can withstand temperature extremes ranging from 1900°F to -140°F (1050°C to -196°C).
- Welding characteristics and weld appearance are exceptional.
