- Applications
- Pumps, valves, pipework and vessels for use in aggressive environments in chemical process plants, also in equipment for flue gas desulphurization and critical equipment in offshore oil and gas production.
- Characteristics
-
- - It can be used for surfacing steels and dissimilar welding of nickel alloys, steels and stainless steels.
- - The weld metal has excellent resistance on pitting and crevice corrosion.
- Notes on Usage
-
- - Use Ar+20~25% CO2 gas.
- - Gas flow rate is proper 20~25ℓ/min.
