DIN 8556 :E 19 9 R 12
prEN 1600 :Application/properties:
This electrode is suitable for welding of austenitic stainless Cr-Ni-Steels, as well as for temperatures up to +350°C; non-scaling up to +800°C. Some of its properties are fine-droplet metal transfer, good wash-in of joint sides, finely-rippled bead surface, easily removable slag, easy arc striking and restriking.
