Gemet 825N, ENiCrMo-3
AWS SFA 5.11 ENiCrMo3
DIN 1736 EL-NiCr20Mo9Nb (2.4621)
Medium heavy coated, basic type, nickel base electrode intended for welding Inconel 625 and similar composition alloys which are primarily used for their excellent corrosion and oxidation resistance.
They exhibit an exceptionally high resistance to pitting corrosion and chloride induced stress corrosion cracking. The electrode is manufactured using nickel-alloyed core wire and hence it is non-synthetic The deposited welds are of x-ray quality.
