Microstructure
Ferrite-Austenite

Special notes
For joint welding on steels of the same type and for highly heat-resistant claddings on normal steels. The weld metal is heat and scale resistant up to 1100°C and resistant to reducing sulphurous furnace gases. Joint welds on steels of the same type are preferably carried out with austenitic MMAs such as MT - 309 L or MT - 310, except for the cover layers. Only the cover layers are welded with MT - 4820 because of the chemical resistance. In this way, greater notch toughness and deformability are achieved.

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