Rutile coated Rod electrodes for welding of stainless austenitic steels. Weld metal made of stabilised austenitic chromium-nickel steel for operating temperatures up to +400°C; scale resistant up to +800°C.

DIN 8556: E 19 9 Nb R 23, material-no.: equivalent to 1.4551, AWS/ASME SFA-5.4: similar to E 347 -16, B.S.2916: 19.9.Nb R, NF A 81-343: EZ 19.9 Nb R 23, EN 1600: E 19 9 Nb R 12.

Most important base materials
Stainless austenitic Cr-Ni steel/cast steel

Microstructure
Austenite with delta ferrite

Special notes
Slag particularly easy to remove. Dark deposit next to the weld can be removed by chloride-free pickling. Weld metal can be polished to a high gloss. Cover insensitive to moisture absorption.

Re-drying
Generally not necessary. However, the cladding can withstand re-drying up to +350°C.
