Nihonweld NSS-2594 description: Coated electrode with an austenitic-ferritic microstructure (duplex – 40% ferrite). The weld metal can be applied for operation temperatures up to 250C and is resistant in chloride containing medias against pitting as well as crevice and stress corrosion. For butt welding and cladding of steels and castings with austenitic-ferritic structure, of the same or similar composition, which are used for pumps, vessels, piping systems etc. attacked by chloride containing solutions. But also for impellers and other components which require hight strength combined with corrosion attack. Pitting index: >40.
