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.

DIN 8556: E 18 8 Mn R 26, material no.: corresponds to 1.4370, AWS/ASME SFA-5.4: similar to E 307 - 16, NF A 81 - 343: EZ 18.8 Mn R 26, EN 1600: E 18 8 Mn R 12.

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.

Microstructure
Austenite, small amounts of delta ferrite possible

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.
