AWS Specification: aws a5.14 ER NiCrMo-4
JIS Specification:

equivalent to INCONEL FM276

Other Specification:

FOR NICKEL ALLOYS

I. APPLICATIONS:

For excellent corrosion resistance to many aggressive media and especially resistant to pitting crevice corrosion.

II. DESCRIPTION:

NT-NiCrMo-4/NM-NiCrMo-4 is used for welding nickel-chromium-

molybdenum alloy (C276) to itself, to steel, to other nickel-base

alloys, and for cladding steel with nickel-chromium-molybdenum

weld metal using the GTAW

and GMAW processes.
