 DIN 8556 : E 19 12 3 Nb R 26
 EN 1600 : E 19 12 3 Nb R 32
 Description and Applications
 Rutile coated austenitic electrode with low carbon stainless core wire, for
 steels to welding austenitic stainless unalloyed or low alloy steels, high
 cracking resistance of the weld metal due to the increased ferrite content.
 Also it is recommended for buffer layers on unalloyed steels prior to
 joining to austenitic grades.
 Distinguished by its outstanding welding characteristics such us excellent
 out of position weldability, good striking and re striking properties, stable
 arc and no spattering, easy slag removal with out residues, homogenous
 and smooth bead resistant to intergranular corrosion up to 400ºC.
