MW-625 is a low Iron Nickel alloy TIG Rod used for 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.
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.
Applications
Some applications that MW-625 can be used for ( Illustrative, not-exhaustive list)
- Welding of nickel-chromium-molybdenum alloys to themselves, to steel a/o to other nickel base alloys.
- Cladding of steel with nickel chromium-molybdenum weld metal.
- Welding of the clad side of joints in steel with nickel-chromium-molybdenum alloy.
- Joining of other nickel alloys where micro-fissuring is problematic.
- Applications in the chemical process industry, in marine engineering and within pollution control equipment.
- Applications where the operative temperature ranges from cryogenic to 540°C;
- For use in high-grade plant/engineering (primarily for the petro-chemical industry).
- High temperature applications such as for exhausts for the racing industry.
