INTRODUCTION
WISDOM ERNiCrMo-3 provides excellent resistance to oxidizing and reducing environments. The high molybdenum content provides good stress, pitting and crevice corrosion resistance. It is used for welding of nickel-chromium-molybdenum alloys. And for cladding and welding dissimilar base metals such as Ni-Cr-Mo alloys to stainless and carbon steels.

APPLICATIONS
· WISDOM ERNiCrMo-3 nickel based welding wire is used for joining and overlaying with INCOFLUX NT100 submerged Arc Flux.
· This alloy can also be used for dissimilar welding using various nickel-chromium-molybdenum alloys and stainless steel, low alloy, and even carbon steels
· WISDOM ERNiCrMo-3 is formulated with low iron (less than 1.0%), and high chromium (over 21.5%) to be an excellent choice for overlaying tubes and tube panels where low dilution of iron and high deposits of chromium are required.
