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)

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 information sheet. Scale resistant. Up to + 850°C.
