FOR NICKEL ALLOYS

I. APPLICATIONS:

For high strength over broad temperature range and exceptional corrosion resistance including pitting and crevice corrosion.

II. DESCRIPTION:

NT-NiCrMo-3/NM-NiCrMo-3 is used for welding nickel- chromium-molybdenum alloy (625) to itself, to steel, to other nickel-base alloys (601 and 800) and for cladding steel with nickel-chromium-molybdenum weld metal and for welding the clad side of joints in steel with nickel-chromium-molybdenum alloy using the GTAW and GMAW processes.
