Characteristics and field of use
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 ½ h followed by cooling in
furnace down to 300 °C and still air.
Base materials
Creep resistant steels and similar alloyed cast steels, case hardening and nitrite able steels of
similar chemical composition, similar alloyed heat treatable steels with tensile strength up to
780 MPa, steels resistant to caustic cracking
