Rutile coated Rod electrodes for vertical-down welding of stainless austenitic steels. Weld metal made of austenitic chromium-nickel-molybdenum steel with particularly low carbon content for operating temperatures up to +400°C, cold-tough down to -120°C.

DIN 8556: E19123LR16, material number: equivalent to 1.4430, AWS/ASME SFA-5.4: similar to E 316 L - 16, B.S.2906: 19.12.3 LR, NFA81 -343: EZ19.12.3LR 16.

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

Microstructure
Austenite with delta ferrite

Special notes
In falling position exact adjustment of welding current is important to avoid overheating of the weld pool. MMA 2.5mm Ø electrodes are particularly suitable for root pass welding in forced positions. The weld metal can be polished to a high gloss.

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