Application/properties:
Electrode for joining of dissimilar steels and for surfacing purposes. The weld metal consists of ferritic-austenitic Cr-Ni-steel with a delta ferrite content of approximately 50% and non-scaling up to 1100°C. It features high resistance to cracking and is therefore indicated for difficult to weld steels and depositing stress-relaxing buffer layers on crack sensitive base metals. It is suitable for welding galvanized steels. Fine droplet metal transfer, good wash-in of joint sides, finely-rippled bead surface, easily removable slag. Easy arc striking and restriking.
