Characteristics and field of use
Basic covered stick electrode for welding 2.25 % Cr 1 % Mo alloyed steels. Approved in long-term
condition up to +600 °C service temperature. Applicable for welds in refineries, boiler construction,
and thermal power plants. Core wire alloyed electrode which will provide reliable creep rupture
properties. 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 nitride-able and heat treatable. Metal recovery approx. 110 %.
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
