Application / Properties: Electrode for joining of dissimilar steels, (austenitic steels to ferritic steels) and for depositing claddings austenitic. weld metal consists of with approximately 15% delta-ferrite. claddings on alloyed or low-alloyed steel are already corrosion resistant in the first layer. highest operating temperature for dissimilar steel joints is +300 C, at higher temperature 1604 G electrode shall be used. fine droplet metal transfer, good wash-in of joint sides, finely-rippled bead surface, easily removable slag. Easy arc striking and restriking.
