Application/properties:
Basic-covered electrode with 63% Ni and 22% Cr and 9% Mo for the welding of:
-Highly corrosion resistant nickel-chromium-molybdenum-alloys, e.g.: NiCr22Mo9Nb(2.4856), NiCr21Mo(2.4858), NiCr22Mo6Cu(2.4618).
-Austenitic steels of highest corrosion resistance, e.g.: 1.4529(X1NiCrMoCuN25206), 1.4547(X1CrNiMoCuN20-18-7)
-Cryogenic nickel-alloyed steels, e.g.: X8Ni9(1.5662)
