Application/properties:
Electrode for welding of austenitic stainless Cr-Ni-Steels having an extra low carbon content, as well as for temperatures up to +350°C; non-scaling up to +800°C. Fine-droplet metal transfer, good wash-in of joint sides, finely- rippled bead surface, easily removable slag. Easy arc striking and restriking.
