Description
Basic electrode for 21/4 % 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.
