Basic stick electrode, low-alloyed, creep resistant.
Characteristics & Applications
Basic electrode for 2.25 % Cr 1 % Mo alloyed boiler, plate and tube steels.
Approved in long-term condition up to +600 °C service temperature.
Core wire alloyed electrode which will provide reliable creep rupture properties for the whole service life of a boiler plant.
Crack resistant and ductile deposit, high creep rupture strength, low hydrogen content (acc. AWS condition HD < 4 ml/100 g).
Good weldability in all positions except vertical down.
Deposit is nitridable and heat treatable.
Metal recovery approx. 115 %. *For step cooling applications we can offer a special product program.
Base Materials
High temperature steels and similar alloyed cast steels, QT-steels similar alloyed up to 980 N/mm2 tensile strength, similar alloyed case hardening steels, nitriding steels.
