Description
Rutile 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.

Most important base materials
Typevarious steels (black/white compounds)high carbon and difficult to weld steel, manganese hard steel e.g. X 120 Mn 12 (1.3401); buffer layers for hard surfacing.

Special notes
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 must be used. Weld metal solidifies during cold forming. Weld metal scale resistant up to +850°C.
Re-drying
Generally not necessary. However, the cladding tolerates re-drying up to +150°C.
