Description
Basic low hydrogen electrode for 1 % Cr 0.5 % Mo alloyed boiler, plate, and tube steels.
Approved in long-term condition up to +570 °C service temperature. Fully alloyed core wire
which will provide reliable creep rupture properties for the whole service life of a boiler plant.
High ductility and crack resistance. The weld metal deposit is heat treatable. Very low hydrogen
content (acc. AWS condition HD < 4 ml/100 g). Metal recovery approx. 115%. Suitable for
step-cooling application. Bruscato ≤15ppm. Post weld tempering at 660-700 °C for at least 1/2
h followed by cooling in furnace down to 300 °C and still air.
