Application/properties:

Electrode for welding of austenitic stainless Cr-Ni-Mo-steels or cast steels having and extra low carbon content. Suitable for operating temperatures up to +400°C. Fine droplet metal transfer, good wash-in of joint sides, finely-rippled bead surface, easily removable slag. Easy arc striking and restriking .
