Basic coated Rod electrodes for joint welding of different types of steel and for weld cladding. Weld metal made of austenitic chromium-nickel-manganese steel for operating temperatures up to +300°C, cold-tough up to -120°C.

DIN 8556: E 18 8 Mn B 20+, material no.: corresponds to 1.4370, AWS/ASME SFA-5.4: similar to E 307 - 15, NF A 81 - 343: EZ 18.8 Mn B 20, EN 1600: E 18 8 Mn B 22.

Most important base materials
Various types of steel (black/white compounds); high carbon and difficult to weld steel, manganese hard steel e.g. X 120 Mn 12 (1.3401); buffer layers for hardfacing, cold toughness steel, e.g. 10 Ni 14 (1.5637), 12 Ni 19 (1.5680)

Microstructure
Austenite, small amounts of delta ferrite possible

Special notes
Suitable for welding steel with higher phosphorus and sulphur content. Highest operating temperature for black/white joints +300°C. For prolonged annealing above +300°C or for operating temperatures above +300°C, nickel-based filler metals should be used. When welding cold-tempered nickel steel, observe the DVS 1501 data sheet. Scale resistant. Up to + 850°C.

Re-drying
Generally not necessary. However, the casing tolerates re-drying up to +350°C.
