316 L (electr.) · 773MTC0005

Rod electrodes for welding stainless austenitic steels. Welding material made of austenitic chromium-nlckel-molybdenum steel with particularly low carbon content for operating temperatures up to +400°C; cold-tough down to -120°C.

DIN 8556: E 19 12 3 LR 23, material-no.: equivalent to 1.4430, AWS/ASME SFA-5.4: similar to E 316 L -16, B.S.2906: 19.12.3.LR, NF A 81-343: EZ 19.12.3 LR 23, EN 1600: E 19 12 3 LR 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. The weld metal can be polished to a high gloss.

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