- Applications
- LNA nickel based alloy with chromium, molybdenum, and tungsten as the principal alloying elements.
- Characteristics on Usage
-
- - It provides a tough Nb-free weld metal for dissimilar welds in superaustenitic and superduplex stainless steel or combinations of these with Ni base alloys.
- - Excellent corrosion resistance in oxidizing as well as reducing media in a wide variety of process environments.
- - Outstanding resistance to stress corrosion cracking, pitting and crevice corrosion.
- Notes on Usage
-
- - Use Ar+20~25% CO2 gas.
- - The optimum flow of CO2 for shielding is 20~25ℓ/min.
- Sizes Available and Recommended Currents ( DC +)
