* Feature
Contains low iron (Fe less than 1%) and is used for welding of nickel-chromium-molybdenum alloys.
Also for cladding and welding dissimilar base metals such as Ni-Cr-Mo alloys to stainless and carbon steels.
The Ni-Cr-Mo alloy system provides excellent resistance to oxidizing and reducing environments. The high molybdenum content provides good stress, pitting and crevice corrosion resistance.
* Application
Used for TIG, MIG and SAW welding of nickel-chromium-molybdenum alloys.
This filler metal may be used for cladding and welding dissimilar base metals such as Ni-Cr-Mo alloys to stainless and carbon steels.
