318 (Electr.) · 776MTC0004

Rutile coated Rod electrodes for welding of stainless austenitic steels. Weld metal made of stabilised chrome-nickel-molybdenum steel for operating temperatures up to +400°C, cold-tough down to -60°C.

DIN 8556: E 19 12 3 Nb R 23+, material no.: equivalent to 1.4576, AWS/ASME SFA-5.4: similar to E 318 - 16, B.S.2906: 19 12 3 Nb R, NF A 81 -343: EZ 19 12 3 Nb R 23, EN 1600: E 19 12 3 Nb R 12.

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

Microstructure
Austenite with delta ferrite

Special notes
Slag particularly easy to remove. Dark coating next to the seam can be removed by chloride-free pickling. Shell insensitive to moisture absorption. Weld metal is not polishable.

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