Description
Basic core wire alloyed electrode for high temperature steels and steels for hot hydrogen service.
Preferably used for X12CrMo5 (5 Cr 0.5 Mo) steels. Approved in long-term condition up to
+650 °C service temperature.
High crack resistance, very low hydrogen content (acc. AWS condition HD < 4 ml/100 g). Good
weldability in all positions except vertical down. The deposit is heat treatable. Metal recovery
approx. 115 %.
