Basic coated electrode for duplex stainless steels
Basic coated electrode with an austenitic - ferritic microstructure (duplex). The weld deposit is characterized by a high resistance against pitting, crevice and stress corrosion in chloride containing media, like sea water, combined with a very high tensile strength. The weld metal can be applied for operation temperatures up to 250°C. For butt welding and cladding of steels and castings with an austenitic- ferritic structure of a similar composition. Easy to weld with, stable arc, easy to remove slag, regular weld beads.
Main applications:
For pumps, vessels, piping systems etc. attacked by chloride containing solutions. But also for impellers and other components which require high strength combined with corrosion attack.
